i40e: move i40e_reset_vf
The VF reset code will be refactored in future patches. Part of that refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so the function must be moved. In order to make the future patches more readable, we perform the function move here, with no other changes.
