[NETFILTER]: nfnetlink_queue: fix EPERM when binding/unbinding and instance 0 exists
Similar to the nfnetlink_log problem, nfnetlink_queue incorrectly returns -EPERM when binding or unbinding to an address family and queueing instance 0 exists and is owned by a different process. Unlike nfnetlink_log it previously completes the operation, but it is still incorrect. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
