notifier: Limit Counter Underflow
When network and service events occur from the bottom up (e.g. supplicant, link state, etc.) that also incur IP configuration changes, it is possible for one or more of the notifier counters to underflow, leaving connman in a state from which it can never recover without a process restart. By limiting underflow of the three notifier counters, these non- recoverable states are prevented.
