mac80211: clarify alignment comment (191922cd) · Commits · e / devices / android_kernel_oneplus_sm7250

The comment says something about __skb_push(), but that isn't even called in the code any more. Looking at the git history, that comment never even made sense when it was still called, so just replace that part to note it still works even when align isn't 0 or 2. Reported-by:
