regulatory: add NUL to alpha2

commit a5fe8e7695dc3f547e955ad2b662e3e72969e506 upstream.

alpha2 is defined as 2-chars array, but is used in multiple
places as string (e.g. with nla_put_string calls), which
might leak kernel data.

Solve it by simply adding an extra char for the NULL
terminator, making such operations safe.
