Improve robustness of network failover

In some cases when remove_network_from_dhcp_agent is called
concurrently by more than one neutron server it leads to unexpected
DB exception when NetworkDhcpAgentBinding is removed.
Need to avoid such case and make remove_networks_from_down_agents
method resistant to such issues by catching broad exception.
