In case of parallel rx execution, fill_count was being updated
by multiple threads and this was causing fill_count to be incorrect
in parallel rx execution cases. This was causing rx ring to be under
filled and in time was causing rx starvation (data stall).
Fix this by:
- making sure that we always fill the right number of buffers based
on the msdu_count in the in_order_indication message.
- making sure that only one execution thread fills the ring
- making sure that the lock holder (filling the ring) does not
run too long by introducing a max fill limit, in which case the
filler will give up and the contender (the other rx execution
thread) takes the lock and fills the ring itself.

Race condition is happening when tx traffic is running and simulataneously
suspend is going on. hdd_hard_start_xmit() is called under txq->__xmit_lock
and in case of low descriptor scenario, it goes to pause the netif queues
and trying to take adapter->pause_map_lock for doing so which is already
acquired by another thread. In another thread, suspend indication is being
preocessed and as a result is trying to pause netif queues with
netif_action WLAN_NETIF_TX_DISABLE which takes adapter->pause_map_lock and
then calls netif_tx_disable() which is trying to take txq->__xmit_lock
already taken by the thread executing hdd_hard_start_xmit(). This leads to
a deadlock situation.
Replace netif_tx_disable() with netif_tx_stop_all_queues() as
netif_tx_stop_all_queues() is doing the same thing as netif_tx_disable()
only without taking the txq->__xmit_lock which prevents this deadlock.

when the segment is added back to the free list. The segment cookie is

The dump_tx_desc function is called to report the number of freed and used
tx descriptors when a suspend is rejected by data path. The debug code
was directly referencing a data field whereas the code to check the freed
and used descriptors used a function that reports a different number under
certain compilation flags. Use the function in the debug statement such that
the value checked is the value printed.

When flow pool is created, pool status is set to FLOW_POOL_ACTIVE_UNPAUSED
irrespective of whether netif queues are paused or not.
Also, when descriptors are transferred from invalid pool to deficient pool,
pool status is not checked. So, if deficient pool is paused, then even
after receiving required descriptors from invalid pool, its status and
netif queues will still remain paused due to which traffic will not be able
to resume ever.
Sync pool status with netif queue status by:
1) Unpausing netif queues as well when pool is created.
2) If deficient pool is paused and on receiving descriptors from invalid
pool, no. of descriptors goes beyond start threshold, unpause the
queues and set the pool status to FLOW_POOL_ACTIVE_UNPAUSED.
