mac80211: do not monitor the connection while scanning
mac80211 constantly monitors the connection to the associated AP
in order to check if it is out of reach/dead.
This is absolutely fine most of the time.
Except when there is a scheduled scan for the whole neighborhood.
After all this path could trigger while scanning on different channel.
Or even worse: this AP probing triggers a WARN_ON in rate_lowest_index
when the scan code did a band transition!
