This is somewhat problematic since no indication of the frame length is
passed in here and we are reading beyond the frame header below.. Maybe
this should use the same style as ieee80211_is_robust_mgmt_frame()
instead, i.e., use skb as the argument and define
_ieee80211_is_group_privacy_action() to take in struct ieee80211_hdr *.

These read the buffer at offset 24, i.e., just after the header. This
should do same as ieee80211_is_robust_mgmt_frame(), i.e., return false
if skb->len < 25.

This looks completely separate item and I don't see why we would even
delete that empty line.. In any case, it should probably not be in this
patch.
