Currently, when adding the 6 GHz Band Capabilities element, the channel list of the wiphy is checked to determine if 6 GHz is supported for a given virtual interface. However, in a multi-radio wiphy (e.g., one that has both lower bands and 6 GHz combined), the wiphy advertises support for all bands. As a result, the 6 GHz Band Capabilities element is incorrectly included in mesh beacon and station's association request frames of interfaces operating in lower bands, without verifying whether the interface is actually operating in a 6 GHz channel. Fix this by verifying if the interface operates on 6 GHz channel before adding the element. Note that this check cannot be placed directly in ieee80211_put_he_6ghz_cap() as the same function is used to add probe request elements while initiating scan in which case the interface may not be operating in any band's channel.
