mesa: don't use format chooser code for glCompressedTexImage
When glCompressedTexImage is called the internalFormat is a specific
format for the incoming image and the the hardware format should be
the same (since we never do format transcoding). So use the simpler
_mesa_glenum_to_compressed_format() function. This change is also
needed for the next patch.
Note: This is a candidate for the stable branches.
