Fix a possible SensorService deadlock.
If the destructor of SensorEventConnection gets called when the main
sendEvents loop of SensorService is executing it may result in a deadlock.
The loop promotes each connection to a strong_pointer, calls sendEvents
and cleans up the connection if necessary. It is possible that the sp's
destructor may delete SensorEventConnection which will call the dtor
~SensorEventConnection(). This dtor again needs SensorService mLock to
execute which may result in a deadlock.
