iwlwifi: clear scanning bits upon failure
In iwl_bg_request_scan function, if we could not send a scan command it will go to done. In done it does the right thing to call mac80211 with scan complete, but the problem is STATUS_SCAN_HW is still set causing any future scan to fail. Fix by clearing the scanning status bits if scan fails. Signed-off-by: Mohamed Abbas <mohamed.abbas@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
