ipa: Fix setting of OPC/DPC based on routing-context + override

As IPA is a transport layer underneath SCCP, and we don't have MTP-level
OPC and DPC fields in it, we are using the "point-code override dpc"
feature for setting the pseudo-M3UA DPC on incoming Rx packets,
and we use the PC from the routing context as pseudo-M3UA OPC.

However, we were so far only storing this in the M3UA data header,
and not in the xua->mtp.{opc,dpc} members, which are consulted
during the routing decisions.
