Subject: [PATCH mlx5-next 1/2] net/mlx5: Add new health syndrome error and crr bit offset

From: Shahar Shitrit <shshitrit@...dia.com>

Add new error value for trust lockdown in health syndrome enum.
Also, include the offset for crr bit in the health buffer layout.

These changes prepare for downstream patches that update health
event handling.
