Since exit always traps into _cleanup function which contains
_cleanup_flakey, don't need _cleanup_flakey twice.

Test that if we create a new hard link for a file which was
previously fsync'ed, fsync a parent directory of the new hard link
and power fail, the parent directory exists after mounting the
filesystem again. The parent directory must be a new directory, not
yet persisted.
This test is motivated by a bug found in btrfs, where the fsync'ed
parent directory was lost after a power failure. The bug in btrfs is
fixed by a patch for the linux kernel titled:
"Btrfs: sync log after logging new name"
