nouveau/vdec: small fixes to h264 handling

nouveau_vp3_inter_sizes requires sliec_count as argument just
as the other places that call it from h264 code do. Hopefully
fixes something.

Fix the status_vp code to allow status == 0 too, when processing
hasn't started yet.

set h264->second_field correctly.
