All xstats names may be retrieved passing NULL ids.
If a driver does not support getting names by IDs, the callback should
return -ENOTSUP on attempt to use it. If so, the request is handled
on ethdev layer by getting all names and filtering out requested only.

The intention is to simplify dev_ops for drivers and have one less dev_ops,
but for xstat_by_id, it is already covered by ethdev layer if PMD doesn't
implement one, so PMD needs to implement them only if it has a better way
to provide _by_id values.
So this merge is bringing an additional check for the ones that doesn't
implement _by_id dev_ops, and for the ones that implement there isn't much
difference, still PMD needs two functions, one for to get all values, and
one for to get _by_id, now although there is single dev_ops, PMD implementation
doesn't differ much.
Because of above reasons I am not sure about this patch, let me proceed with
rest of the series, we can discuss this patch more separately.
