In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: don't get the radio mask for netdev-less wdevs
cfg80211_calculate_bi_data() calls rdev_get_radio_mask() with
wdev->netdev, which can be NULL and then crashes in mac80211.
To avoid that, invert the order of checks since wdev->netdev
is always valid for beaconing interfaces.
