i965: Use the renderbuffer surface size instead of region size for WM surfaces.

For drawing to lower mipmap levels, the region size makes the renderbuffer
be the size of the lowest level, instead of the current level.  On DRI1,
Brian previously found that the RB size was incorrect, so leave this broken
there.
