Rather than querying the output device for its address in mctp_local_output, set up the source address when we're populating the dst structure. If no address is assigned, use MCTP_ADDR_NULL. This will allow us more flexibility when routing for NULL-source-eid cases. For now though, we still reject a NULL source address in the output path. We need to update the tests a little, so that addresses are assigned before we do the dst lookups.
