mesa: push row stride adjustment down into _mesa_decompress_image()

There's a mismatch in row strides for compressed textures between
what Driver.MapTextureImage() returns and what the software fetch-texel
functions use.  Move it down a layer.  The next step would be to fix
this in the fetch-texel functions.
