[QNS] Stop monitoring thresholds for EIMS when data disconnected.

- When cellular is unavailable, CellularQuailtyMonitor will clear
requests to telephonyCallBack.
- When cellular become available again, other APns will reset the
threshold by calling unregisterThresholdToQualityMonitor. For
Emergency, according to current design, in some case, the
threshold will not be reset as QNS only handles HO of Emergency
data connection.
- In result, CellularQuailtyMonitor will not listen to
telephonyCallBack, until the set of threshold values is changed.
