BACKPORT: motion_sense: Force flush when sensor disabled.
When sensor is disabled, HAL will not send flush request to EC.
However, when sensor is reenabled, only new events are expected.
When we have a change in frequency, we have to request the host to
query all the current events.
Flush the FIFO when events are not needed because all sensors are
disabled.
BRANCH=smaug, cyan
TEST=Pass more tests: tests like ..._fastest_batching after _50hz_flush
have more change to pass.
