intel: When validating an FBO's combined depth/stencil, use the given FBO.

We were looking at the current draw buffer instead to see whether the
depth/stencil combination matched.  So you'd get told your framebuffer
was complete, until you bound it and went to draw and we decided that
it was incomplete.
