netfilter: ctnetlink: fix GFP_KERNEL allocation under spinlock
The previous fix for the conntrack creation race (netfilter: ctnetlink: fix conntrack creation race) missed a GFP_KERNEL allocation that is now performed while holding a spinlock. Switch to GFP_ATOMIC. Reported-and-tested-by: Zoltan Borbely <bozo@andrews.hu> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
