4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paulo Alcantara <palcantara@suse.com>
commit c988de29ca161823db6a7125e803d597ef75b49c upstream.
Make sure to use the CIFS_DIR_SEP(cifs_sb) as path separator for prefixpath too. Fixes a bug with smb1 UNIX extensions.
