composite: Fix pWin->redirectDraw when changing between manual and automatic redirection 

compAllowPixmap() is not called when changing between manual and
automatic redirection modes. That means pWin->redirectDraw is left
with an incorrect value, and miComputeClips() gets confused whether
the window is supposed to be treated as transparent or not. Fix
the issue by updating pWin->redirectDraw in compCheckRedirect()
even when not calling compAllocPixmap().
