ikev2: fix lookup in wrong ip table

In responder mode we need to remember interface index from which IKE session was initiated. Otherwise when sending keep alive packets to the initiator, the default ip table is always used for lookup instead of the one associated with the interface. Type: fix Change-Id: Iade3fc3a490b7ae83c3f6e9014d1f4204e476ac1 Signed-off-by: Filip Tehlar <ftehlar@cisco.com>
