    wlan - Don't check bgscanidle setting in net80211 for full-offload scan.
    
    * If full-offload scan is used, the NIC driver (or rather the firmware of
      the NIC) should take care of interrupting and continuing the background
      scan. So net80211 should ignore the vap->iv_bgscanidle setting then,
      instead the NIC driver might look at this setting and pass it on to the
      firmware in some way if possible.
    
    * Since full-offload scans won't be explicitly interrupted by net80211, it
      also doesn't really make sense to check the vap->iv_bgscanidle condition
      in that case, before starting a background scan. If the NIC driver
      advertises background scan support and full-offload scanning, the firmware
      should be able to execute that scan without interfering too much with our
      data traffic.
