net/mlx5: cmdif, Refactor error handling and reporting of async commands
Same as the new mlx5_cmd_do API, report all information to callers and
let them handle the error values and outbox parsing.
The user callback status "work->user_callback(status)" is now similar to
the error rc code returned from the blocking mlx5_cmd_do() version,
and now is defined as follows:
-EREMOTEIO : Command executed by FW, outbox.status != MLX5_CMD_STAT_OK.
Caller must check FW outbox status.
0 : Command execution successful, outbox.status == MLX5_CMD_STAT_OK.
< 0 : Command couldn't execute, FW or driver induced error.
