avcodec/mpegvideo_enc: Remove redundant emms_c

Browse Source 
It is unnecessary since d91b1559e0
(before that the sad_cmp[0] call in get_intra_count() may
have clobbered the floating point state without cleaning it up
itself).

Also remove some commented out emms_c from places where
the floating point state is guaranteed not to have been clobbered
by us.
