[RFC 2/3] fs: use SB_NOUSER on path_mount() instead of deprecated MS_NOUSER

[Luis Chamberlain <mcgrof@kernel.org>]

The goal behind 462ec50cb5 ("VFS: Differentiate mount flags (MS_*) from
internal superblock flags") was to phase out MS_* users for internal
uses. But we can't remove the old MS_* until we have all users out so
just use the SB_* helper for this check.
