[XFRM]: Fix aevent related crash
When xfrm_user isn't loaded xfrm_nl is NULL, which makes IPsec crash because xfrm_aevent_is_on passes the NULL pointer to netlink_has_listeners as socket. A second problem is that the xfrm_nl pointer is not cleared when the socket is releases at module unload time. Protect references of xfrm_nl from outside of xfrm_user by RCU, check that the socket is present in xfrm_aevent_is_on and set it to NULL when unloading xfrm_user.
