Fix the sensor framework timer issue reported by #884 when setting `ms_to_next_check`, and unify the type of time related args/vars to uint32 to avoid potential type conversion issues, and fix the compile warnings. And update the sensor sample by creating two sensors to confirm that the fix works correctly.
