Fix regression introduced by -machine accel=
Commit
85097db6 changed the timing when kvm_allowed is set until after
kvm is initialized. During initialization, the ioeventfd initialization code
checks kvm_enabled() and after this change, ioeventfd is effectively disabled.
This causes a significant regression in performance.

virtio-serial-bus: use bh for unthrottling
Instead of calling flush_queued_data when unthrottling, schedule
a bh. That way we can return immediately to the caller, and the
flush uses the same call path as a have_data for callbackee.
No migration change is required because bh are called from vm_stop.

scsi: Use 'SCSIRequest' directly
Currently the SCSIRequest structure is abstracted away and cannot accessed
directly from the driver. This requires the handler to do a lookup on
an abstract 'tag' which identifies the SCSIRequest structure.
With this patch the SCSIRequest structure is exposed to the driver. This
allows use to use it directly as an argument to the SCSIDeviceInfo
callback functions and remove the lookup.
A new callback function 'alloc_req' is introduced matching 'free
req'; unref'ing to free up resources after use is moved into the
scsi_command_complete callbacks.
This temporarily introduces a leak of requests that are cancelled,
when they are removed from the queue and not from the driver. This
is fixed later by introducing scsi_req_cancel. That patch in turn
depends on this one, because the argument to scsi_req_cancel is a
SCSIRequest.
