libsensors: fix poll event that would use 100% CPU
The new MPLSensor.cpp's readEvents() does not really read events :(
it just ignores the data field and always return 0 no matter what.
But it does mess around with some MPLSensor internal data and reads
iio buffers.
The MPLSensor's executeOnData() reads events and returns data.
Based on the comments of that function it should be called after reading
an event.
It was placed in the code such that it would always return an available
event even of the poll didn't return anything.
This would cause poll(,,0) and nothing ever waited.
Switch the sensor logging back to verbose to avoid polluting logcat.
