i40e hardware descriptor fields are in little-endian format. Driver
must use le32_to_cpu while evaluating these fields otherwise on
big-endian arch we end up evaluating incorrect values, cause errors
like:
i40evf 0001:04:02.0: Expected response 0 from PF, received 285212672
i40evf 0001:04:02.1: Expected response 0 from PF, received 285212672
