avcodec/av1: only set the private context pix_fmt field if get_pixel_format()
succeeds
Otherwise get_pixel_format() will not be called when parsing a subsequent
Sequence
Header in non hwaccel enabled scenarios, allowing frame parsing when it
shouldn't.
This prevents the scenario seqhdr -> frame_hdr/redundant_frame_hdr -> seqhdr ->
redundant_frame_hdr from having the latter redundant frame header parsed as if
it
was a frame header by the decoder because the former was discarded.
Since CBS did not discard it, the latter redundant frame header is output with a
zeroed AV1RawFrameHeader struct, which can have undesired results, like division
by zero with fields normally guaranteed to be anything else.
Fixes: division by zero
