DcTracker: Cleanup connections when IccRecords is destroyed.

The IccRecords are destroyed when the SIM goes through a state change like a
refresh reset. Attempting to setup data connections when in this case can lead
to incorrect APNs being passed to the radio.

The change will cleanup all data connections when IccRecords are disposed off.
New data connections will not be setup because SIM ready checks are done
before setting them up.
