net/mlx4: Support shutdown() interface
In kexec scenario, we failed to load the mlx4 driver in the second kernel because the ownership bit was hold by the first kernel without release correctly. The patch adds shutdown() interface so that the ownership can be released correctly in the first kernel. It also helps avoiding EEH error happened during boot stage of the second kernel because of undesired traffic, which can't be handled by hardware during that stage on Power platform.
