xfrm: Access the replay notify functions via the registered callbacks

[ Upstream commit 1265fd616782ef03b98fd19f65c2b47fcd4ea11f ]

We call the wrong replay notify function when we use ESN replay
handling. This leads to the fact that we don't send notifications
if we use ESN. Fix this by calling the registered callbacks instead
of xfrm_replay_notify().
