qcacmn: Fix invalid osif_vdev issue

Currently as part of TDLS connection if TLDS connection is formed
on secondary vdev, osif_vdev of secondary vdev is updated with
osif_vdev of primary vdev.
Due to osif_vdev update, during vdev delete 1st vdev will call
API to free osif_vdev. When 2nd vdev try to access the osif_vdev
it will result in invalid pointer access.

As current change was done to handle case where osif_vdev
for MLO connection used to point to 2 different interfaces
and where secondary interface used to point to NULL/dummy netdev.
As per latest change osif_vdev will point to per vdev dp_link
which for MLO connection will have single interface. So osif_vdev
update is not required anymore.

So, to fix invalid/stale pointer issue remove osif_vdev update for
TDLS connection.

first_msdu_payload is updated for every WIFIRX_HEADER_E
TLV received in the status nbuf and this could result

if the PPDU has multiple MPDUs. Also, the size variable
used is 8 bit for the calculation of offset into the nbuf
for the frame which could result in possible overflow.

Fix is to update first_msdu_payload only for the first
WIFIRX_HEADER_E TLV entry for a PPDU and increase the
width of size variable to avoid possible integer overflow.

qcacmn: Optimize force free logic in dp_find_missing_tx_comp()

Currently during runtime suspend, in dp_find_missing_tx_comp(),
TX descriptors are freed forcefully if the TX completions for
those descriptors do not arrive within 60 seconds.

In certain rare corner cases, there is a chance of TX buffer (that is
in the enqueue path) getting freed in the TX completion path due to
delayed completions. This results in NULL pointer dereference.
Following is the sequence of events for such a case,

1. dp_find_missing_tx_comp() frees a TX descriptor
2. Different buffer gets attached to the same TX descriptor
3. Delayed completion for the previous TX arrives and frees
the buffer in point 2.

Defer the free in dp_find_missing_tx_comp() when there is a delta in
HP/TP for the TX/COMP rings. If HP & TP are not same, then there is
high chance of processing the delayed completion beforehand, thus
avoiding the aforementioned race.
