A hack that when restartRadio is called the CdmaDataConnectionTracker

to retry a connection and possibly reconnect after a temporary data loss.

The root cause appears to be because DEACTIVATE and POWER_RADIO_OFF are
sent back to back and POWER_RADIO_OFF completes before DEACTIVATE.
When this happens CdmaDataConnectionTracker won't attempt to reestablish
a data connection until a voice call terminates.

At this time it appears the better solution is have CdmaDataConnectionTracker
wait for DEACTIVATE to complete before issuing POWER_RADIO_OFF, this fix
will be implemented in the near future.
