net/iavf: fix default RSS hash for IP fragments

Previously, hash value is calculated by src IP address, dst IP address
and IP ID. However, default RSS field only needs src and dst IP address.

This patch removes IP ID from default RSS field for IP fragment packets
to improve default RSS configuration.
