qcacld-3.0: Add link switch in progress for peer delete cmd

For secondary (partner) VDEV, upon receiving peer delete request
from host, FW will immediately send peer delete response even
before the peer delete handshake with HW is completed.

This approach is brought in for two link association teardown
where starting a peer delete timer on partner link VDEV down may
result in timeout, if the assoc link peer delete is not received
before the timer expires.

To avoid this case, FW will only start peer delete timer during
primary (assoc) VDEV down and sends the peer delete response once
it is actually deleted in the system.

Now with three link support, if there is link switch on partner VDEV,
FW is sending peer delete response immediately (even if the delete is
still ongoing) to host and host is proceeding with MAC address update
and new peer create (with new link id) causing FW to assert as peer
delete on that VDEV is in progress.

Add new flag to indicate whether link switch in progress during
current peer delete WMI cmd. If this flag is set, FW will not send
peer delete response immediately but wait for the delete handshake
to complete with HW.
