scsi: qla2xxx: Fix session hang in gnl

Browse Source 
Connection does not resume after a host reset / chip reset. The cause of
the blockage is due to the FCF_ASYNC_ACTIVE left on. The gnl command was
interrupted by the chip reset. On exiting the command, this flag should be
turn off to allow relogin to reoccur. Clear this flag to prevent blockage.
