[Mesa-dev] [PATCH 12/29] mesa: Fix RGBA8888_UINT direct unpack path in _mesa_format_convert.

[Iago Toral Quiroga]

A direct unpack to this format from a signed format won't clamp so we should
not resolve converts of this kind via the unpack fast path. These scenarios
will be handled properly by mesa_swizzle_and_convert path.
