mesa: Switch generate_mipmaps_compressed() to using TexImage2D to upload.
The code was playing fast and loose with rowstrides, which meant that if a driver chose anything different for its alignment requirements, the generated mipmaps came out garbage. Unlike the uncompressed case, we can't generate mipmaps directly into image->Data, so by using TexImage2D we cut out most of the weird logic that existed to generate in-place into ->Data. The up/downside is that the driver recovery code for the fact that _mesa_generate_mipmaps whacked ->Data has to be turned off for compressed now. Fixes 6 piglit tests about compressed mipmap gen.
