The e774ad683f425a51f87711164ea166d9dcc41477 commit made this function
return proper error codes instead of NULL. Reflect that.
This is a fix for a NULL dereference introduced in
21abb1ec414c75abe32c3854848ff30e2b4a6113:
echo "$SOME_IPV6_ADDR \"test" > /smack/ipv6host
(this should return EINVAL, it doesn't)
cat /smack/ipv6host
(derefences 0x000a)
