Validate the ip addresses added to the DHCP server

Browse source 
DHCP server certainly needs the IP address configured in order to lease
the address to the client. There is a bug in NM which wrongly removes
all addresses on the unmanaged interface while it should not. To
guarantee the IP address indeed configured for DHCP server, rescue it
via adding conditional loop for configuring IP address to DHCP server.

Notice that this workaround will be removed eventually when NM fixes
the bug.
