regulatory: add NUL to request alpha2
Similar to the ancient commit a5fe8e7695dc ("regulatory: add NUL to alpha2"), add another byte to alpha2 in the request struct so that when we use nla_put_string(), we don't overrun anything. Fixes: 73d54c9e74c4 ("cfg80211: add regulatory netlink multicast group") Reported-by: Kees Cook <keescook@google.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
