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.
