vfio/mlx5: Protect mlx5vf_disable_fds() upon close device
Protect mlx5vf_disable_fds() upon close device to be called under the
state mutex as done in all other places.
This will prevent a race with any other flow which calls
mlx5vf_disable_fds() as of health/recovery upon
MLX5_PF_NOTIFY_DISABLE_VF event.
Encapsulate this functionality in a separate function named
mlx5vf_cmd_close_migratable() to consider migration caps and for further
usage upon close device.
