datapaths with big dpid will cause an overflow

Attempting to create a datapath with dpid larger than 0x7fffffffffffffff will cause an overflow.
e.g.
% vnctl datapaths add --uuid=dp-test --display-name=test --dpid=0xdeadbeefdeadbeef --node-id=vna
This generates :dpid: '0x7fffffffffffffff'.
The type of DATAPATHS.dpid should be unsigned?
