Roam_synch indication processing in host performs peer detach/attach
operations after firmware has already moved to the new peer. Out of
sequence peer unmap and map events can mess up the reference count
for reused peer_id values, which can lead to crash.
Solution:
While detaching a peer during roam sync indication processing,
copy its peer_id_ref_cnt in peer_id_to_obj array to new variable
in the same peer map for that peer id. Peer is deleted at that point.
When the unmap events come in, decrement the old ref_cnt and
map events increment the real ref_cnt.
Once the old ref_cnt goes to 0, subsequent unmap operations apply to
the real peer.

In current codeflow, we are maintaining the length of the TSO segments
belonging to one jumbo packet inside tso_info, which is common for
all the segments of one jumbo packet. This works if the length of
the segments (frag[1]) is the same. In case it is not, it ends up
assigning incorrect length to all the segments. This is resulting
GMS login failure.
Fix issue by maintaining the total length of the segment in the
qdf_tso_seg_t structure.

A race condition has been observed between outgoing TX traffic and
peer deletion when DUT has concurrent SAP(DBS) and STA sessions in 5G
and 2G respectively and the peer connected to SAP moves away triggering
peer deletion at DUT. Due to peer being deleted, the vdev corresponding
to the peer is void which results in a crash in ol_tx_data function
while trying to send Tx data.
