avcodec/mpegvideo_enc: Remove redundant checks for multithreading 

The generic code ensures that only codecs with
the FF_CODEC_CAP_AUTO_THREADS internal cap ever have to
handle the case avctx->thread_count == 0 themselves;
moreover, it is also ensured generically that only codecs
that support some form of threading have thread_count set
to something else than one. So these checks are unnecessary.
