i965/pixel_read: Don't try to do a tiled_memcpy from a multisampled buffer
The GL spec guarantees that glGetTexImage will never get a multisampled texture, but this is not true for glReadPixels. If we get a multisampled buffer, we have to do a multisample resolve on it before we can pull the data down for the user. Since this isn't practical to handle in tiled_memcpy, we just fall back to the other paths that can handle this. Reviewed-by: Kenneth Graunke <[email protected]>
