Andreas Rheinhardt e5a33c898a avcodec/mpegvideo: Only keep the actually used unquantize funcs ...

For all encoders and all decoders except MPEG-4 the unquantize
functions to use don't change at all and therefore needn't be
kept in the context. So discard them after setting them;
for MPEG-4, the functions get assigned on a per-frame basis.

Decoders not using any unquantize functions (H.261, MPEG-1/2)
as well as decoders that only call ff_mpv_reconstruct_mb()
through error resilience (RV30/40, the VC-1 family) don't have
the remaining pointers set at all.
