Subject: [PATCH] bitrate: add sanity check on parameters

[ upstream commit 90b0e5aaf4e3a56a4dac57aceb425930450cec85 ]

If rte_stats_bitrate_reg() or rte_stats_bitrate_calc() are
passed NULL as the parameter for the stats structure, the
result is a crash. Fixed by adding a sanity check that makes
sure the passed-in pointer is not NULL.

Fixes: 2ad7ba9a6567 ("bitrate: add bitrate statistics library")
