Eric W. Biederman 44f79df28b exec: Simplify unshare_files ...

[ Upstream commit 1f702603e7125a390b5cdf5ce00539781cfcc86a ]

Now that exec no longer needs to return the unshared files to their
previous value there is no reason to return displaced.

Instead when unshare_fd creates a copy of the file table, call
put_files_struct before returning from unshare_files.
