SELinux: renumber the superblock options
Just to make it clear that we have mount time options and flags, separate them. Since I decided to move the non-mount options above above 0x10, we need a short instead of a char. (x86 padding says this takes up no additional space as we have a 3byte whole in the structure) Signed-off-by: Eric Paris <eparis@redhat.com>
