staging: wlags49_h2: buffer overflow setting station name

commit b5e2f339865fb443107e5b10603e53bbc92dc054 upstream.

We need to check the length parameter before doing the memcpy().  I've
actually changed it to strlcpy() as well so that it's NUL terminated.

You need CAP_NET_ADMIN to trigger these so it's not the end of the
world.
