iwlwifi: mvm: prevent sched scan while not idle
Prevent sched scan while not idle (including during association or in AP mode) instead of while associated only. This fixes my previous commit which was incomplete: commit bd5e4744a6ca64299b57a2682c720d00a475a734 Author: David Spinadel <david.spinadel@intel.com> Date: Thu Apr 24 13:15:29 2014 +0300 iwlwifi: mvm: do no sched scan while associated Currently the FW doesn't support sched scan while associated, Prevent it.
