[Mesa-dev] [PATCH] mesa: Use the format info to identify packed depth/stencil formats.

[Nick Bowler]

Due to a misunderstanding of the Z24_X8 and X8_Z24 formats, the earlier
patch created depth/stencil wrappers for them.  This broke swrast.

Use the format info instead, which only identifies Z24_S8 and S8_Z24 as
packed depth/stencil.  It also has the advantage of being nicer code.
