[sensorservice] Fix inconsistent states in SensorDevice

[sensorservice] Fix inconsistent states in SensorDevice

This CL avoids inconsistent disabled client list when sensorservice
is in restricted mode and a restricted sensor event connection is
destroyed.

The inconsistency can cause registerLister error in sensor CTS.

Also removed the additional logging message since they are no longer
necessary.

Bug: 28533594

Test: Running "cts-tradefed run singleCommand cts-dev --module
CtsHardwareTestCases --test android.hardware.cts.SensorBatchingTests"
continuously while keep registering and unregistering sensor listener
in a separate app (e.g. enable BreakIt mode in SensorLogger).
