Subject: [PATCH net-next 2/4] net/mlx5: Log health buffer data on any syndrome

From: Moshe Shemesh <moshe@...dia.com>

Currently health buffer data is logged either when FW fatal error
detected or miss counter reached max misses threshold.

Log health buffer whenever new health syndrome is detected.
