media: rkvdec: h264: Fix reference frame_num wrap for second field

When decoding the second field in a complementary field pair the second field is sharing the same frame_num with the first field. Currently the frame_num for the first field is wrapped when it matches the field being decoded, this cause issues to decode the second field in a complementary field pair. Fix this by using inclusive comparison, less than or equal. Signed-off-by: Jonas Karlman <[email protected]>
