FDIR Rx ring isn't initialized and Rx queue HW tail isn't updated
when there's error detected during programming FDIR flow. There'll
be some potential risk.
This patch updates FDIR Rx resource.
Fixes: a778a1fa2e4e ("i40e: set up and initialize flow director")
Fixes: 05999aab4ca6 ("i40e: add or delete flow director")

v2 change:
- Correct HW tail.
