Shuhei Matsumoto 50ec73894c iscsi: Support SCSI port removal when PG map is removed
Currently even if PG mapping is removed from iSCSI target,
corresponding SCSI port is not removed. Hence dynamic
reconfiguration of PG to existing iSCSI target is not supported.

This patch supports dynamic SCSI port removal when the
corresponding PG mapping is removed from the existing target.

Some refactoring for SCSI port addition is also done
