Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within dp replace any such comparisons with logical
operations performed on the pointer itself.

qdf_nbuf_cat API used to call skb_free
on src address but was later modified
so that the caller of qdf_nbuf_cat is
responsible for freeing the src memory
Due to this change in the API, the
freeing of src memory on caller side
was not taken care and will lead to
mem leak
Hence add qdf_nbuf_free after calling
qdf_nbuf_cat if it returns success.
If qdf_nbuf_cat returns failure, then
freeing is taken care as part of error
handling in parent function.

In Repeater configuration when a STA first associates to Root AP
on some radio and then roams quickly to repeater AP on other radio,
some times target assert is observed due to below race condition.
1. Root AP sends peer delete command to FW on radio X and clears
its AST entry. This peer delete command not processed by FW yet.
2. STA roames to repeater AP and starts ping traffic to Root AP.
3. Root AP receives the ping frame and tries to add wds entry on
radio Y as AST entry was not found.
4. FW receives add wds entry on radio Y while on radio X an
direct peer ast entry for same mac was present.
5. FW asserts.

Currently while reaping the rxda destination ring in dp_rx_mon_mpdu_pop,
we end up un-mapping the nbuf twice when -
1. msdu_ppdu_id > ppdu_id
2. msdu_ppdu_id = ppdu_id
For case 1, we exit from the dp_rx_mon_mpdu_pop without reaping the
descriptor completely, but we unmap the nbuf corresponding to it.
Next, when case 2 happens, we end up un-mapping the nbuf again to reap
the same descriptor.
Introduce a flag in the rx_desc to keep track of un-mapping the nbuf. If
the nbuf is already unmapped, donot unmap it.

multicast loopback packet from one station vap should not come into

with the source address of the packet.
Also added a new vdev parameter to check if qwrap isolation mode is
enabled. In qwrap isolation mode, loopback packets should not be
