decoder: h264: fix processing of EOSEQ NAL.

Browse source 
Fix decoding of end_of_seq() NAL unit so that to not submit the current
picture for decoding again. This is pretty vintage code that dates back
before the existing of the whole decoder units machinery.

One issue that could be arising if that code was kept is that we could
have submitted a picture, and subsequently a GstVideoCodec frame, twice.
Once without the decode_only flag set, and once with that flag set. The
end result is that the GstVideoDecoder would release the codec frame
twice, thus releasing stale data.

In short, the piece of code that is removed by this patch is for once
completely obsolete for a while, and secondly error-prone in corner
cases.
