ipv6: Refactor fib6_ignore_linkdown
fib6_ignore_linkdown takes a fib6_info but only looks at the net_device and its IPv6 config. Change it to take a net_device over a fib6_info as its input argument. In addition, move it to a header file to make the check inline and usable later with IPv4 code without going through the ipv6 stub, and rename to ip6_ignore_linkdown since it is only checking the setting based on the ipv6 struct on a device.
