net/mlx5: Provide simplified command interfaces
Many mlx5_cmd_exec() callers are not interested in the output from that
command or have standard in/out structures. Those callers simply allocate
those structure on the stack and use sizeof() to provide in/out arguments.
In this naive approach provide simplified versions of mlx5_cmd_exec().
