Subject: [PATCH] [VP] fix crash in vp8 playback.

Inserting an already registered surface creates new index
without removing old, as the surface is already registered
in table no need to register , remove RegisterRTSurfaces.

fixes vp8 decoding crash in chromeos,ffmpeg 4.2 vp8 decoding
works fine in kbl/cml/jsl.
