ionic: Fix check in ionic_get_link_ext_stats

Browse Source 
The current check will fail if SR-IOV is not initialized for the
physical function; this is because is_physfn is 0 if sriov_init() isn't
run or fails. Change the check that prevents getting the link down count
to use is_virtfn instead so that VFs don't get this functionality, which
was the original intent.

Fixes: 132b4ebfa0 ("ionic: add support for ethtool extended stat link_down_count")
