lwtunnel: fix error path in lwtunnel_fill_encap()
We recently added a check to see if nla_nest_start() fails. There are
two issues with that. First, if it fails then I don't think we should
call nla_nest_cancel(). Second, it's slightly convoluted but the
current code returns success but we should return -EMSGSIZE instead.
