(vfprintf): Only call __libc_cleanup_region_end if USE_IN_LIBIO,
	thus matching the sense of the tests around
	__libc_cleanup_region_start at the front of the function.
	* stdio-common/vfscanf.c: Include <libc-lock.h>.
	(UNLOCK_STREAM) [! USE_IN_LIBIO]: Call
	__libc_cleanup_region_end, not __libc_cleanup_region_start.
