net/nfnetlink: lockdep_nfnl_is_held can be boolean
This patch makes lockdep_nfnl_is_held return bool to improve readability due to this particular function only using either one or zero as its return value. No functional change. Signed-off-by: Yaowei Bai <bywxiaobai@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
