libceph: fix uninitialized value when no get_authorizer method is set
If there is no get_authorizer method we set the out_kvec to a bogus pointer. The length is also zero in that case, so it doesn't much matter, but it's better not to add the empty item in the first place. Signed-off-by: Sage Weil <sage@newdream.net>
