i40e: fix the restart auto-negotiation after FEC modified
When FEC mode was changed the link didn't know it because
the link was not reset and new parameters were not negotiated.
Set a flag 'I40E_AQ_PHY_ENABLE_ATOMIC_LINK' in 'abilities'
to restart the link and make it run with the new settings.
Fixes: 1d96340196f1 ("i40e: Add support FEC configuration for Fortville 25G")
