vfio/mlx5: Add support for tracker object change event

Browse source

Add support for tracker object change event by referring to its
MLX5_EVENT_TYPE_OBJECT_CHANGE event when occurs.

This lets the driver recognize whether the firmware moved the tracker
object to an error state.

In that case, the driver will skip/block any usage of that object
including an early exit in case the object was previously marked with an
error.

This functionality also covers the case when no CQE is delivered as of
the error state.

The driver was adapted to the device specification to handle the above.
