sccp: MTP-TRANSFER.req: Set OPC before route lookup
Before this commit, all SCCP UNIT-DATA.req came with unset xua->mtp.opc
and hence route lookup was done with opc=0 in mtp route label.
Since loadsharing may take into account some OPC bits to distribute
traffic, set the OPC properly before route lookup.
