Dan Carpenter 39f3709599 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.
