Remove another 2 incorrect checks.
These would ignore fields of different parity.
I was wrong, i thought pic_stricture is the current pic structure.
But it does not make a difference either way on the reference bitstreams.

Setting chroma_qp to 0 for PCM blocks is really an interesting minor

optimization, more interresting would it have been had the author
thought about what value chroma_qp would have for the following MB.
Or failing that, had actually tested the code.
