Eric W. Biederman 1f702603e7 exec: Simplify unshare_files 
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.
