Andrew Morton a3c65022d8 mm: revert "mm: shmem: fix data-race in shmem_getattr()" ...

commit d1aa0c0429 upstream.

Revert d949d1d14f ("mm: shmem: fix data-race in shmem_getattr()") as
suggested by Chuck [1].  It is causing deadlocks when accessing tmpfs over
NFS.

As Hugh commented, "added just to silence a syzbot sanitizer splat: added
where there has never been any practical problem".
