[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. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
