It turns out there is at least one more bug in ieee80211_sta_tx_notify(), introduced in commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing"), where we forgot to check for the QoS variant and so assumed the QoS nullfunc frame never went out Fix this by adding a helper ieee80211_is_any_nullfunc() which consolidates the check for non-QoS and QoS nullfunc frames. Replace existing compound conditionals and add a couple more missing checks for QoS variant.
