regulatory: add NUL to request alpha2

Browse Source 
[ Upstream commit 657308f73e674e86b60509a430a46e569bf02846 ]

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")
