Kaustubh Pandey a607d76b50 net: core: null pointer derefernce in sockev_client_cb 
sockev_client_cb creates a netlink message and populates
the nlmsg_data using the socket->sock information.
If socket is closed, while the nlmsg_data is being
populated, a null pointer dereference occurs.

BUG: KASAN: null-ptr-deref in sockev_client_cb+0x1e4/0x310
