iwlwifi: mvm: fix race in queue notification wait

Initially in this code, the race didn't matter since it didn't
do anything. Latest with the commit I marked this as fixing it
started to matter as something got done here that needed other
data that got freed as soon as the queue notification wait was
returning.

In the scenario we saw, apparently the IWL_MVM_RXQ_NOTIF_DEL_BA
event was sent to all queues, but processing the last event we
returned from iwl_mvm_sync_rx_queues_internal() and then from
iwl_mvm_free_reorder() and continued some processing before
wl_mvm_del_ba() was even invoked on the other CPU. Thus, when
the latter finally ran, it found that mvm->baid_map[baid] was
no longer valid.

Correct the race by moving the counter decrement and wake_up()
to be done only after all the per-event processing completed.
Note that in the commit I marked as being fixed the wake_up()
didn't exist yet (and the code was otherwise problematic) but
this particular problem already existed in a way.

In order to realize the keep-alive mechanism in mac80211 stack, reporting
accurate tx ack status for nullfunc frame is added in this commit.

If current frame is nullfunc frame, we ask firmware to report by filling
TX report bit in TX descriptor. After this frame DMA done, TX interrupt is
triggered but TX status is unknown at this moment, so enqueue this skb
into tx_report->queue. Finally, C2H report will be received if the frame
is transmitted successfully or retried over, and then we report to mac80211
with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if

During the RX leg driver needs to fetch the ethernet header
length from the RX'ed Buffer Descriptor. Currently, proprietary
version hns3_nic_get_headlen is being used to fetch the header
length which uses l234info present in the Buffer Descriptor

Kernel default eth_get_headlen API does the job correctly.

r8169: fix network error on resume from suspend

This commit removed calls to rtl_set_rx_mode(). This is ok for the
standard path if the link is brought up, however it breaks system
resume from suspend. Link comes up but no network traffic.

Meanwhile common code from rtl_hw_start_8169/8101/8168() was moved
to rtl_hw_start(), therefore re-add the call to rtl_set_rx_mode()
there.

Due to adding this call we have to move definition of rtl_hw_start()
after definition of rtl_set_rx_mode().

handled.  BSO has 4 possible values:
  00 --> Good frame with no error, or unknown integrity
