Send empty LinkProperties when entering StoppedState.
Test: as follows
- built
- flashed
- booted
- runtest frameworks-net passes
- changing from DHCPv4 to static while continuously pinging the
default gateway works jsut fine
- dumpsys log shows that during the change we send the empty LP:
12-06 08:46:51.085 - CMD_ON_QUIT wlan0/23 0 0 null [rcvd_in=StoppingState, proc_in=StoppingState]
12-06 08:46:51.092 - INVOKE onLinkPropertiesChange({{InterfaceName: wlan0 LinkAddresses: [] Routes: [] DnsAddresses: [] Domains: null MTU: 0}})
