[PATCH v3 5/6] composite: Fix pWin->redirectDraw when changing between manual and automatic redirection

[ville.syrjala at nokia.com]

From: Ville Syrjälä <ville.syrjala at nokia.com>

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().
