Subject: [PATCH] metrics: disallow null as metric name

[ upstream commit 219731302a0aa5b8edb30a6bc1cdea64e7824a98 ]

This patch adds a sanity check so that names passed into
rte_metrics_reg_names() and the wrapper rte_metrics_reg_name()
cannot be NULL.

Fixes: 349950ddb9c5 ("metrics: add information metrics library")
