inet: Avoid potential NULL peer dereference.
We handle NULL in rt{,6}_set_peer but then our caller will try to pass that NULL pointer into inet_putpeer() which isn't ready for it. Fix this by moving the NULL check one level up, and then remove the now unnecessary NULL check from inetpeer_ptr_set_peer(). Reported-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
