> The mlx5_flow_action_copy_mreg structure contains a field called src

> The flow_mreg_add_copy_action function sets a variable of struct

> similarly the flow_create_split_metadata function sets a variable of

> In both functions, they initialize a enum modify_reg type variable with

> Replace assigning 0 with REG_NONE in both functions.
