Clear the information of the underlying network
The NetworkCapabilities and LinkProperties of the underlying
network should be cleared when there is a new underlying network.
Currently, Vpn.java only clear both NetworkCapabilities and
LinkProperties of the underlying when onLost() is called or when
the VPN is disconnected. But onLost() won't be fired if the device
is connected to mobile data first, then connects to wifi later.
For this case, both mUnderlyingNetworkCapabilities and mUnderlyingLinkProperties keep the old value until onLinkPropertiesChanged() and onNetworkCapabilitiesChanged() are
called.
