iwlwifi: work around passive scan issue
Some firmware versions don't behave properly when passive scanning is requested on radar channels without enabling active scanning on receiving a good frame. Work around that issue by asking the firmware to only enable the active scanning after receiving a huge number of good frames, a number that can never be reached during our dwell time.
