Florian Westphal 6a13f5afd3 xfrm: policy: fix null dereference 
Julian Wiedmann says:
> +     if (!xfrm_pol_hold_rcu(ret))

Coverity spotted that ^^^ needs a s/ret/pol fix-up:

> CID 1599386:  Null pointer dereferences  (FORWARD_NULL)
> Passing null pointer "ret" to "xfrm_pol_hold_rcu", which dereferences it.

Ditch the bogus 'ret' variable.

Fixes: 563d5ca93e ("xfrm: switch migrate to xfrm_policy_lookup_bytype")
