net/i40e: fix multiple DDP packages conflict

Should be not possible to load conflicting DDP profiles. Only DDP
profiles of the same group (not 0) can be loaded together. If DDP
profile group is 0, it is exclusive, i.e. it cannot be loaded with
any other DDP profile. If DDP profile groups are different, these
profiles cannot be loaded together.
