Don't crash if the interface disappears just after appearing.

If the interface disappears between interfaceAdded() and
setInterfaceUp, we'll crash with an IllegalStateException in
NetworkManagementService#setInterfaceConfig.

Ignore the error instead. This should be safe because we don't
modify any state unless our calls succeed.
