Remove the flag gating logging and fix a bug.

This flag was needed for gating the raw sensor data collection, which is
now moved to somewhere else.

Calling evaluateRotationChangeLocked() before setting
mDesiredRotation = reportedRotation is meaningless since it always
returns -1, so that is also removed.

Test: statsd_testdrive on Redfin
