r600g: fix copying between NPOT mipmapped compressed textures
We aligned the dimensions to the blocksize, then divided by it
(in r600_blit.c), then minified, which was wrong.
The minification must be done first, not last.
This fixes piglit/fbo-generatemipmap-formats with S3TC and maybe
a bunch of other tests too. Tested on RV730.
