st/mesa: fix mipmap generation bug
In st_finalize_texture() we were looking at the st_texture_object:: lastLevel field instead of the pipe_resource::last_level field to determine which resource to store the mipmap in. Then, in st_generate_mipmap() we need to call st_finalize_texture() to make sure the destination resource is properly allocated. These changes fix the broken piglit fbo-generatemipmap-formats test.
