Uoti Urpala 803dc1fb8a vo_vdpau: fix preemption recovery after recent commits 
Recent commits for screenshot support and video redraw changes didn't
handle vdpau driver preemption state correctly, which could make the
player crash if preemption occurred. Fix this and improve preemption
handling a bit otherwise.
