[SCSI] qla2xxx: Mark a port's state as needing-rediscovery during link disruptions.

With RSCN states not being kept across qla2x00_configure_loop()
invocations, loop-resync distruptions during fabric-discovery may
cause ports to remain in a lost state.  Force state
renegotiation during a follow-on configure-loop iteration.
