iwlegacy: 3945: fix hw passive scan on radar channels
commit 68acc4afb040d98ddfd2cae0de09e2f4e1ee127f upstream.
Patch fix firmware error on "iw dev wlan0 scan passive" for
hardware scanning (with disable_hw_scan=0 module parameter).

We have disable ability to change passive scanning to active on
particular channel when traffic is detected on that channel. Otherwise
firmware will report error, when we try to do passive scan on radar
channels.
