backports: Make ieee80211_tx_status handling work on older kernel versions
The commit f02dff93e26b ("mac80211: extend ieee80211_tx_status_ext to
support bulk free") makes use of the list attribute in the skb, but this
is not available in kernel < 4.19, use the sk_buff_head instead on these
kernel versions.
