[PATCH net-next] audit: pass int* to nlmsg_next

[Alexandru Copot <alex.mihai.c@gmail.com>]

Commit 941912133025926307c7a65b203fa38403b1063a replaced the macros
NLMSG_NEXT with calls to nlmsg_next which produces this warning:

kernel/audit.c: In function ‘audit_receive_skb’:
kernel/audit.c:928:3: warning: passing argument 2 of ‘nlmsg_next’ makes pointer from integer without a cast
In file included from include/net/rtnetlink.h:5:0,
                 from include/net/neighbour.h:28,
                 from include/net/dst.h:17,
                 from include/net/sock.h:68,
                 from kernel/audit.c:55:
include/net/netlink.h:359:1: note: expected ‘int *’ but argument is of type ‘int’

Fix this by sending the intended pointer.
