I don't think this can happen or make sense to add "just in case".

Minimum mtu is 28 (coverity probably doesn't know that), and usually more like
~1400.

Max vp8_hdr_len is 4, so smallest packet_len passed to
gst_rtp_buffer_calc_payload_len() is 24. csrc_count and pad_len are always 0
here, and GST_RTP_HEADER_LEN is 12.

(>=24) < 12 -> always false.
