From: Qiushi Wu <wu000273@umn.edu>
commit febfd9d3c7f74063e8e630b15413ca91b567f963 upstream.
In function mlx4_opreq_action(), pointer "mailbox" is not released, when mlx4_cmd_box() return and error, causing a memory leak bug. Fix this issue by going to "out" label, mlx4_free_cmd_mailbox() can free this pointer.
