We've traced down all code paths where NetworkInfo.isRoaming() and
NET_CAPABILITY_NOT_ROAMING can disagree, so we're only left with
noise that happens from NetworkAgent race conditions when someone
asks for a NetworkState between pending NetworkInfo and
NetworkCapabilities updates.
We can look at adding a way for a NetworkAgent to update these
two objects atomically, but not for this release.
