The crash occurs in the core_tpg_del_initiator_node_acl() function
and a call to that function has been added recently in
target_fabric_nacl_base_release(). I think it was added through the
following patch:

commit c7d6a803926bae9bbf4510a18fc8dd8957cc0e01
Date:   Mon Apr 13 19:51:14 2015 +0200

    target: refactor init/drop_nodeacl methods
    
    By always allocating and adding, respectively removing and freeing
    the se_node_acl structure in core code we can remove tons of repeated
    code in the init_nodeacl and drop_nodeacl routines.  Additionally
    this now respects the get_default_queue_depth method in this code
    path as well.
