Currently, we decrement active_work_cnt in a while loop in delayed
register worker and later on make a "allow_l1" call to enable L1ss.
The bus suspend routine depends on the value of active_work_cnt to
determine if any register writes are pending. In case there are, bus
suspend is rejected.
As a result its possible that when bus suspend happens, the
delayed worker while processing the last remaining enqueued
write, makes the active_work_cnt to 0. This will allow the bus suspend
routine to continue to disable the bus, even before the
delayed-reg-worker has called allow_l1 and run to completion. This may
lead to a NOC error while calling "allow_l1" API from
delayed-reg-worker.
Hence, move the decrement of active_work_cnt to the very end in
hal_reg_write_work function.

Delayed register write work needs to be flushed before bus suspend to
make sure there are on pending writes after driver's bus suspend routine
exits. In case delayed work context is not able to finish before the bus
(PCI) is suspended (DRV), it may lead to a NOC error.

Nbufs are reused on non-monitoring status ring, so stale
values will still be present in the status ring nbufs post
channel change. A possible scenario where after mon channel
is changed to 5G from 2G, MAC-0 status ring is processed and
buffer_done tlv tag could be read from the stale nbuf even
though HW does not set this for the latest packet. This could
result in un-map and free of the status_nbuf even before HW
updates the buffer_done tlv tag.
Fix is to replenish buffers instead of re-using the buffers
when reaping non-monitoring status ring.

TSO packet segments are enqueued to the HW individually.
The skb users count is incremented for each additional
segment, so that it is freed only when the TX completion
for the last segment is received.
Currently the skb users is incremented for the additional
TSO segments after the previous segment has been enqueued
to the HW. Due to this, there is a chance for the tx
completion for the first TSO segment to be received even
before the skb users is incremented to account for the
remaining TSO segments, thereby leading to use-after-free
scenarios.
Fix this by incrementing the skb users for additional
TSO segment before enqueueing the previous TSO segment
to the HW.
