[dpdk-dev] [PATCH v1] lib/metrics: fix silent fail when uninitialised

> If rte_metrics_init() had not been called and hence the internal
> metric storage is not allocated, rte_metrics_get_values() and
> rte_metrics_get_name() would silently fail by returning zero
> (i.e. no metrics registered). This patch changes the result of
> this scenario to an explicit fail by returning -EIO.
