mesa: Fix glCompressedTexSubImage (and non-Sub) for height == 2 or 1.
Generally this code works with width and height aligned to compressed
blocks, but at the 2x2 and 1x1 levels of a square texture (or height <
bh in general), we were skipping uploading our single row of blocks.
Fixes piglit compressedteximage GL_COMPRESSED_RGBA_S3TC_DXT5_EXT.
