This patch encompasses a few fixes carried by a previous patch
that aimed to support bonding device stats counting.
- If mlx5_os_read_dev_stat fails, it returns 1 instead of a
negative value, causing mlx5_xstats_get to return an invalid
number of counters. Since this error is not blocking, do not
mess ret value with mlx5_os_read_dev_stat returned value.
This allows avoiding the very annoying log:
"n_xstats != n_xstats_names => skipping"
- Invert the check for mlx5_os_read_dev_stat(), currently leading
us to store the result if the function failed, and use a
backup value if it succeeded, which is the opposite of what we
actually want. Revert to the original (correct) test.
- Add missing test on _mlx5_os_read_dev_counters() to prevent
using trash stats values.
