  avcodec/x86/vp3dsp_init: Set correct function pointer, fix crash
  
  Regression since fd172185580c1ccdcfb90bbfdb59fa806fad3117;
  triggered by vp4/KTkvw8dg1J8.avi in the FATE suite, but not
  when running fate as this code is not used when the bitexact
  flag is set.
  
  Bisecting done by ami_stuff, patch from user Mika Fischer
  in ticket #10027 (which this commit fixes).

  lavc/rv40dsp: R-V V chroma_mc
  
  This is similar to h264, but here we use manual_avg instead of vaaddu
  because rv40's OP differs from h264. If we use vaaddu,
  rv40 would need to repeatedly switch between vxrm=0 and vxrm=2,
  and switching vxrm is very slow.
