scsi: hisi_sas: fix the risk of freeing slot twice

The function hisi_sas_slot_task_free() is used to free the slot and do
tidy-up of LLDD resources. The LLDD generally should know the state of
a slot and decide when to free it, and it should only be done once.

For some scenarios, we really don't know the state, like when TMF
timeout. In this case, we check task->lldd_task before calling
hisi_sas_slot_task_free().

However, we may miss some scenarios when we should also check
task->lldd_task, and it is not SMP safe to check task->lldd_task as we
don't protect it within spin lock.

This patch is to fix this risk of freeing slot twice, as follows:

  1. Check task->lldd_task in the hisi_sas_slot_task_free(), and give
     up freeing of this time if task->lldd_task is NULL.

  2. Set slot->buf to NULL after it is freed.

scsi: hisi_sas: fix SATA breakpoint memory size

Currently the size of memory we allocate for SATA breakpoint buffer is
incorrect.

The breakpoint memory size should be as follows: 32 (NCQ tags) * 128 *
2048 (max #devs) = 8MB

Currently we only allocate 0.5MB, but get away with it as we never
have SATA device index > 128 typically.

To conserve precious DMA memory (8MB may not be even available), limit
the number of devices per HBA to 1024, which means 4MB of memory
required for SATA breakpoint.

scsi: megaraid_sas: Add support for 64bit consistent DMA

The latest MegaRAID Firmware (for Invader series) has support for 64bit
DMA for both streaming and consistent DMA buffers.  All Ventura series
controller FW always support 64 bit consistent DMA.  Also, on a few
architectures 32bit DMA is not supported.

Current driver always prefers 32bit for consistent DMA and 64bit for
streaming DMA.  This behavior was unintentional and carried forwarded
from legacy controller FW. Need to enhance the driver to support 64bit
consistent DMA buffers based on the firmware capability.

Below is the DMA setting strategy in driver with this patch.  For
Ventura series, always try to set 64bit DMA mask. If it fails fall back
to 32bit DMA mask.  For Invader series and earlier generation
controllers, first try to set to 32bit consistent DMA mask irrespective
of FW capability. This is needed to ensure firmware downgrades do not
break. If 32bit DMA setting fails, check FW capability and try seting to
64bit DMA mask.

There are certain restrictions in the hardware for having all sense
buffers and all reply descriptors to be in the same 4GB memory region.
This limitation is h/w dependent and can not be changed in firmware.
This limitation needs to be taken care in driver while allocating the
buffers.  There was a discussion regarding this - find details at below
link.  https://www.spinics.net/lists/linux-scsi/msg108251.html

scsi: libcxgbi: simplify task->hdr allocation for mgmt cmds

In case of mgmt cmds, task->hdr is dereferenced after transmitting the
pdu in iscsi_tcp_task_xmit(). To handle this case current code
increments the Tx skb reference count and frees the skb in
cxgbi_cleanup_task(). In some error cases this results in skb leak.

To fix this in case of mgmt cmds, allocate a separate buffer for iSCSI
hdr and free this buffer in cxgbi_cleanup_task().
