ice: add link_down_events statistic
Introduce a link_down_events counter to the ice driver, incremented
each time the link transitions from up to down.
This counter can help diagnose issues related to link stability,
such as port flapping or unexpected link drops.
The value is exposed via ethtool's get_link_ext_stats() interface.
