target: Make TFO->check_stop_free return free status
This patch converts target_core_fabric_ops->check_stop_free() usage in transport_cmd_check_stop() and associated fabric module usage to return '1' when the passed se_cmd has been released directly within ->check_stop_free(), or return '0' when the passed se_cmd has not been released. This addresses an issue where transport_cmd_finish_abort() -> transport_cmd_check_stop_to_fabric() was leaking descriptors during LUN_RESET for modules using ->check_stop_free(), but not directly releasing se_cmd in all cases.
