scsi: qedf: Stop sending fipvlan request on unload
- On some setups fipvlan can be retried for long duration and the
connection to switch was not there so it was not getting any reply.
- During unload this thread was hanging.
Problem Resolution:
Check if unload is in progress, then quit from fipvlan thread.
