gallium/radeon: return correct values for BE in r600_translate_colorswap

Browse source 
Because I changed the swizzle check, I also need to adapt the return
values for each check.

It's basically almost the same as before, we just cross between STD and
STD_REV, and cross between ALT and ALT_REV

This fixes the rgba test in gl-1.0-readpixsanity (piglit) and also
fixes tri-flat (mesa demos).
