Update peer DB as per new design
peer_hash_table: add at peer_create and delete at peer delete
peer_id_to_obj_map: add at peer map and delete at peer unmap
peer_list: vdev level peer list add at peer create delete at
peer delete
Call dp_peer_cleanup() at unmap event
dp_peer_cleanup -> dp_peer_tx_cleanup -> Tx capture cleanup

---------> dp_peer_rx_cleanup -> Cleanup Rx REO TID queues &
defrag queue free
Introduce ref_cnt variable per VAP which will be
incremented and decremented at peer alloc and free. This counter
will be used to delay the vdev free if there are any active
peers for vdev exist in system

Remove the global soc->peer_ref_mutex lock to protect
peer access
Instead use granular locks to protect the individual
peer DBs
1) soc→peer_hash_lock : To protect peer hash table
2) soc→peer_map_lock : To protect id to objmap array
3) vdev→peer_list_lock : To protect vdev level peer list

In dp_srng_init, max_buffer_length and prefetch_timer are used
while uninitialized.
In dp_bucket_index, overrunning array cdp_sw_enq_delay leads to
out-of-bounds access.
In dp_rx_defrag_fraglist_insert, cur is first NULL checked but
cur is again set to qdf_nbuf_next and is accessed without
NULL check. Thus do a NULL check again before dereferencing
cur to avoid potential NULL pointer dereference.
In htt_t2h_stats_handler, soc could be NULL while cmn_init_done
is dereferenced. Thus fix it by NULL check soc first and then
dereference cmn_init_done.

Fix static analysis issue of rx_refill_buf_ring buffer overflow.
rx_refill_buf_ring length is different for WIN/MCL. For MCL length is 1,
WIN is 3. So rx_refill_buf_ring should always use index pdev->lmac_id to

In case of driver unload, there can be a race condition
since the timer for processing monitor status ring can run
in parallel to the unload time wow ack response handler,
which is also flushing all the monitor status ring entries.
To avoid this race condition, stop the monitor reap timer
as a part of target suspend, and process all the outstanding
entries in the montior status ring.
This will make sure that the monitor status ring is
processed from only one context at any given time.
