Retry ducking deactivation when it is failed

Retry ducking deactivation when it is failed

- Issue:
Sometimes ducking deactivation can be failed and does not recovered.

- Solution:
This patch adds the logic for retrying ducking deactivation if the
deactivation is failed. In most case, deactivation is not failed because
previous logic also calcualtes the ducking duration. However, some
unknown reason, deactivation can be failed. So this patch makes the
framework handle this situation.
