mac80211: fix the skb cloned check in the tx path
Using skb_header_cloned to check if it's safe to write to the skb is not
enough - mac80211 also touches the tailroom of the skb.
Initially this check was only used to increase a counter, however this
commit changed the code to also skip skb data reallocation if no extra
head/tailroom was needed:

mac80211: skip unnecessary pskb_expand_head calls
It added a regression at least with iwl3945, which is fixed by this patch.
