vfio/mlx5: Handle the EREMOTEIO error upon the SAVE command

The SAVE command uses the async command interface over the PF.

Upon a failure in the firmware -EREMOTEIO is returned.

In that case call mlx5_cmd_out_err() to let it print the command failure
details including the firmware syndrome.

Note:
The other commands in the driver use the sync command interface in a way
that a firmware syndrome is printed upon an error inside mlx5_core.
