target: Drop unused legacy target_core_fabric_ops API callers
This patch drops the following unused legacy API callers from target_core_fabric.h: *) TFO->fall_back_to_erl0() *) TFO->stop_session() *) TFO->sess_logged_in() *) TFO->is_state_remove() This patch also removes the stub usage in loopback, tcm_fc, iscsi_target, and ib_srpt fabric modules.
