fix an issue where SensorService could request an invalid sensor delay

Browse Source 
When the app requests "fastest", the java layer encodes this as a
delay of 0. SensorService was passing this unchanged to the HAL.
However the HAL is required to reject delays lower that the
advertised lower delay.
