wifi: mac80211: don't use rate mask for scanning
The rate mask is intended for use during operation, and
can be set to only have masks for the currently active
band. As such, it cannot be used for scanning which can
be on other bands as well.
Simply ignore the rate masks during scanning to avoid
warnings from incorrect settings.
