core: Allow to handle destination null and broadcast endpoint id
mctp daemon might query endpoint (i.e., get endpoint id command)
by physical addressed requests and set destination eid as 0.
Current implementation will block handling destination null and
broadcast endpoint id for MCTP control message type.
