4.1-stable review patch. If anyone has any objections, please let me know.

From: Avraham Stern <avraham.stern@intel.com>
commit e9cb0327b26dd7ba43a3b7a05b4b62219decf42d upstream.
The csa_countdown flag was not cleared when the AP is stopped. As a result, if the AP was stopped after csa_countdown had started, all the folowing channel switch commands would fail. Fix that by clearing the csa_countdown flag when the AP is stopped.
