Commit message: staging: wlags49_h2: buffer overflow setting station name

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.

CVE: CVE-2013-4514
CWE: CWE-119
Vulnerability description: Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions.
