[SCSI] libfc: do not log off rports before or after discovery
When receiving an RSCN, do not log off all rports. This is extremely disruptive. If, after the GPN_FT response, some rports haven't been listed, delete them. Add field disc_id to structs fc_rport_priv and fc_disc. disc_id is an arbitrary serial number used to identify the rports found by the latest discovery. This eliminates the need to go through the rport list when restarting discovery.
