lavc/hevcdec: do not pass a pixel format to set_sps()

It is merely copied to AVCodecContext.pix_fmt, which serves no useful
purpose. set_sps() is called from two places:
* when a new SPS becomes active - then the pixel format is
  overridden immediately after the set_sps() call by the result from
  ff_get_format();
* when a new SPS is propagated across frame threads - then the
  AVCodecContext value is already set to the same value by the generic
  code.
