Scenario: In case of STA + STA, NB/SB issues disconnection for
vdev 0 when vdev 1 is in connecting state.
As connection is blocking serialization command and it can try
multiple candidates and can take upto 30+ sec, there is a
chance that disconnect may get timeout and is followed by
vdev delete from osif. This can lead to vdev delete sent
without vdev down/stop and bss peer delete for vdev 0.
So abort connection when trying for candidate if any of the
vdev is waiting for disconnect, to avoid disconnect timeout.
