To handle features like PGRs in userspace we need the entire iniaitor
port id. For iscsi that is defined as the initiator name plus the
session identifier. The session id is hidden from users, because
its internal to the drivers, so this patch separates the acl name
from the SCSI port ids.
This will then allow other drivers like SRP to use different values
like the port id or src address for the ACL, but then use the port
id for transport ID checks in target_core_fabric.c.
This will also be used to export the initiator info in the session's
sysfs dir in the last patches, so tools like tcmu-runner can rebuild
its session state used when handling PGR commands.
