Johannes Berg 31beefbf14 BACKPORT: nl80211: correctly check NL80211_ATTR_REG_ALPHA2 size
commit 6624bb34b4eb19f715db9908cca00122748765d7 upstream.

We need this to be at least two bytes, so we can access
alpha2[0] and alpha2[1]. It may be three in case some
userspace used NUL-termination since it was NLA_STRING
(and we also push it out with NUL-termination).
