Re: [PATCH]: net: ipv6: fix oops in inet_putpeer()

The attached patch fixes an oops in inet_putpeer(). Please see the
changelog entry for details.

An alternative fix would be to check whether rt6_peer_ptr() returns
NULL before invoking inet_putpeer(), but properly initializing the
peer looks cleaner to me.

This is fine for now, applied, thanks Patrick.

There was a built-in assumption that xfrm_fill_dst() would run to
completion before we'd try to release these things, because there in
xfrm6_policy.c's xfrm6_fill_dst, we'd do the rt6_transfer_peer().

But that's obviously not the case if errors happen meanwhile.
