i40e: Add a FD flush counter to ethtool
This helps know how many times the interface had to flush and replay FD
filter table, which gives an indication on how often we are getting FD
table full situation.
Also check on certain pf states before proceeding to add or delete
filters since we can't add or delete filters if we are in those states.
