Fix race condition in network scheduling to dhcp agent

Rarely dhcp agent rpc call get_active_networks_info() can interleave
with network scheduling initiated by create.port.end notification.
In this case scheduling raises and port creation returns 500.
Need to synchronize on DhcpNetworkBindings table.

Closes-Bug: #1276552
