vo_opengl: vdpau: fix certain cases of preemption recovery failures

The vdpau_mixer could fail to be recreated properly if preemption
occured at some point before playback initialization (like when using
--hwdec-preload and the opengl-cb API).

Normally, the vdpau_mixer was supposed to be marked invalid when the
components using it detect a preemption, e.g. in hwdec_vdpau.c. This one
didn't mark the vdpau_mixer as invalid if preemption was detected in
reinit(), only in map_image().

It's cleaner to detect preemption directly in the vdpau_mixer, which
ensures it's always recreated correctly.
