*** empty log message ***
(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.
