    mac80211: util: don't warn on missing sband iftype data
    
    The kernel currently floods the ringbuffer with warnings when adding a
    mesh interface for a device not support HE 6GHz modes.
    
    Return without warning in this case, as mesh_add_he_6ghz_cap_ie calls
    ieee80211_ie_build_he_6ghz_cap regardless of the supported interface
    modes.
