#### rtp_engine.c: Prevent segfault in ast_rtp_codecs_payloads_unset()
  Author: George Joseph

  There can be empty slots in payload_mapping_tx corresponding to
  dynamic payload types that haven't been seen before so we now
  check for NULL before attempting to use 'type' in the call to
  ast_format_cmp.

  Note: Currently only chan_sip calls ast_rtp_codecs_payloads_unset()
