Log Message

Add back the setDelay function

According to https://source.android.com/devices/sensors/versioning

"Implement the batch function

... It replaces setDelay. setDelay will not be called anymore."

However, it is wrong. The setDelay is still called sometimes
as show in the system_server crashing log:
