Jann Horn 53e21cfa68 filelock: Fix fcntl/close race recovery compat path

commit f8138f2ad2 upstream.

When I wrote commit 3cad1bc010 ("filelock: Remove locks reliably when
fcntl/close race is detected"), I missed that there are two copies of the
code I was patching: The normal version, and the version for 64-bit offsets
on 32-bit kernels.
Thanks to Greg KH for stumbling over this while doing the stable
backport...

Apply exactly the same fix to the compat path for 32-bit kernels.

Fixes: c293621bbf ("[PATCH] stale POSIX lock handling")
