the functions will be called based on the status of the flag
created. This flag will be enabled by default.

In tx desc store vdev_id to avoid unprotected access of
vdev memory.
In tx path pass VDEV as argument to all APIs
In completion path get vdev from peer as vdev reference
in peer is protected with reference, in places where peer
is invalid get vdev object using vdev_id stored in tx desc
with a reference count

CE2 status ring full condition results in WMI req timeout
in host resulting in self recovery being triggered.
Set IRQ affinity of CE IRQs to gold cores for defconfig
builds only. This is to alleviate the processing of all
DP rings and CE rings on CPU0.
CE2 status ring will be reaped fast enough to ensure host
has enough credits from FW to send out the WMI reqs to FW.

Add new APIs to iterate through the vdev peer list
by taking the peer reference.
A call back has to be passed to these APIs which will
be called for every peer in the lisst
dp_vdev_iterate_peer() -> iterates through peer_list of vdev
dp_pdev_iterate_peer() -> iterates through peer_list of all
vdevs in pdev
dp_soc_iterate_peer() -> iterates through peer_lists of all vdevs
in soc
Additonal APIs are added to for itearations where the callback
will be called outside the vdev->peer_list_lock, as these APIs
have additional memory allocations suggested to use only in case
the iteration need to happen outside lock
dp_vdev_iterate_peer_lock_safe()
dp_pdev_iterate_peer_lock_safe()
dp_soc_iterate_peer_lock_safe

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.
