dummy: expend mtu range for dummy device

After commit 61e8462 ("net: centralize net_device min/max MTU checking"), the mtu range for dummy device becomes [68, 1500]. This patch extends it to [0, 65535]. Signed-off-by: Zhang Shengju <zhangshengju@cmss.chinamobile.com> Signed-off-by: David S. Miller <davem@davemloft.net>
