i965: Fix incorrect bounds tracking for blit readpixels's GPU access.
While incorrect, it probably wouldn't affect anyone ever: You'd have to do
an appropriately-formatted readpixels into a PBO, then overwrite the tail
end of the updated area of the PBO with glBufferSubData(), and you
wouldn't get appropriate synchronization.
