avcodec/mpegvideo_enc: Remove redundant pixel format checks

All encoders using ff_mpv_encode_init() already have pix_fmts set
so that the pixel format is already checked in ff_encode_preinit().
The one exception to this is MJPEG whose check remains.

(Btw: The AVCodec.pix_fmts check for AMV is stricter than the check
in ff_mpv_encode_init().)
