cifs: escape spaces in share names
Commit 653a5efb849a ("cifs: update super_operations to show_devname") introduced the display of devname for cifs mounts. However, when mounting a share which has a whitespace in the name, that exact share name is also displayed in mountinfo. Make sure that all whitespace is escaped.
