Commit: 6c09e79 ("cfg80211: Allow NL80211_ATTR_IFINDEX to be added
to vendor events")
This commit add parameter wdev to cfg80211_vendor_event_alloc(), that would
be used to check at __cfg80211_alloc_vendor_skb() to assign ifindex to
the skb and is merged in Kernel 4.1, so add a kernel version macro to
support this
Also merge the hdd_vendor_put_ifindex into cfg80211_vendor_event_alloc
to assign the ifindex when wdev is given, that way we can unify the interface.
