ionic: add support for ethtool extended stat link_down_count
Following the example of 'commit 9a0f830f8026 ("ethtool: linkstate:
add a statistic for PHY down events")', added support for link down
events.
Add callback ionic_get_link_ext_stats to ionic_ethtool.c to support
link_down_count, a property of netdev that gets reported exclusively
on physical link down events.
Run ethtool -I <devname> to display the device link down count.
