Subject: [PATCH 4/4] [LIO-Target]: Add iscsi_get_fabric_proto_ident() for EVPD PIV=1 usage

This patch adds the SPC-4 defined PROTOCOL IDENTIFIER value for
iSCSI (0x5) in iscsi_get_fabric_proto_ident(), which is attached to
struct target_core_fabric_ops->get_fabric_proto_ident() during
LIO-Target v3.0 module registration with Target_Core_Mod/ConfigFS.
