mesa/st: swap order of clear() and clear_with_quad() 

If we can't clear all the buffers with pctx->clear() (say, for example,
because of ColorMask), push the buffers we *can* clear with pctx->clear()
first.  Tilers want to see clears coming before draws to enable fast-
paths, and clearing one of the attachments with a quad-draw first
confuses that logic.
