l1sap: make send_ul_rtp_packet_hrdata() NULL-safe
lchan->abis_ip.rtp_socket is NULL before the BSC indicates the RTP
parameters using the CRCX/MDCX procedures. send_ul_rtp_packet()
does check lchan->abis_ip.rtp_socket against NULL before calling
osmo_rtp_send_frame_ext(), so should send_ul_rtp_packet_hrdata().
Take a chance to make send_ul_rtp_packet_hrdata() more consistent
with the send_ul_rtp_packet() by reordering code a bit.
