Commit b592211c ("dm mpath: fix attached_handler_name leak and dangling hw_handler_name pointer") fixed a memory leak for the case where setup_scsi_dh() returns failure. But setup_scsi_dh may return success and not "use" attached_handler_name if the retain_attached_hwhandler flag is not set on the map. As setup_scsi_sh properly "steals" the pointer by nullifying it, freeing it unconditionally in parse_path() is safe.
