From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch updates tcm_loop_tpg_alloc_fabric_acl() and tcm_loop_tpg_release_fabric_acl()
to follow TCM v4.0 convention for alloc/release of the demo mode se_node_acl_t used for
the TCM_Loop virtual SAS Initiator Ports. This includes hanging struct se_node_acl_s
off the fabric dependent struct tcm_loop_nacl so that container_of() macros can be used
to access internal structures in tcm_loop from struct se_node_acl_s presented pointers.
Also, this patch removes the legacy usage of fabric->reg_default_groups_callback() in
tcm_loop_register_configfs().
