Subject[PATCH 3.16 267/305] cifs: Fix separator when building path from dentry
3.16.63-rc1 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.

Fixes: a6b5058fafdf ("fs/cifs: make share unaccessible at root level mountable")
