netpoll: remove return value from netpoll_rx_disable()
The netpoll_rx_disable() will always return 0, it is no use and looks wordy, so remove the unnecessary code and get rid of it in _dev_open and _dev_close. Signed-off-by: Ding Tianhong <dingtianhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
