This series improves the mlx5 driver to better handle some error cases
as of below.
The first two patches let 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.
The next two patches (#3, #4), improve the driver to better include the
proper firmware syndrome in dmesg upon a failure in some firmware
commands.
The last patch follows the device specification to let the firmware know
upon leaving PRE_COPY back to RUNNING. (e.g. error in the target,
migration cancellation, etc.).
This will let the firmware clean its internal resources that were turned
on upon PRE_COPY.
Note:
As the first patch should go to net/mlx5, we may need to send it as a
pull request format to vfio before acceptance of the series, to avoid
conflicts.

Patch #2:
- Rename to use 'object changed' in some places to make it clearer.
- Enhance the commit log to better clarify the usage/use case.
The above was suggested by Tian, Kevin <kevin.tian@xxxxxxxxx>.
this series looks good to me except a small remark on patch2:
We should be fine there, see my answer on V0.
