net: fix nla_policy_len to actually _iterate_ over the policy
Currently nla_policy_len always returns n * NLA_HDRLEN: It loops, but does not advance it's iterator. NLA_UNSPEC == 0 does not contain a .len in any policy. Trivially fixed by adding p++. Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com> Signed-off-by: David S. Miller <davem@davemloft.net>
