Jason Ekstrand 3a2977e7b5 anv: Reject modifiers on depth/stencil formats 
6790397346 added code which attempts to reject modifiers on
depth/stencil formats but it was placed after the early return for depth
and stencil aspects.  This commit moves it up so it actually works.

Of course, this doesn't actually matter because the only user of any of
the modifiers stuff is the WSI code and it will never do anything with
depth/stencil.
