It is possible that the host queued the peer delete command to FW
but no peer delete event was received within the peer delete
timeout as FW initiated a UMAC reset.
When the vdev mgmt response timer times out, check if umac reset is in
progress. If so, restart the vdev mgmt response timer.
The entire umac reset handshake completes within 200ms if not
FW asserts. Hence no need to add the count check before
restarting the vdev mgmt response timer.
