The mlx5_flow_action_copy_mreg structure contains a field called src
type enum modify_reg, similarly the mlx5_rte_flow_item_tag field
contains a field called id type enum modify_reg.
The enum modify_reg variable represents different registers in the
system and it also has a field called REG_NONE whose value is 0 which
means that the register does not exist.
The flow_mreg_add_copy_action function sets a variable of struct
mlx5_flow_action_copy_mreg type, and initializes the src field to be 0.
Similarly the flow_create_split_metadata function sets a variable of
struct mlx5_rte_flow_item_tag type and initializes the id field to be 0.
In both functions, they initialize a enum modify_reg type variable with
an int type value while modify_reg has an appropriate field for that
value (REG_NONE).
Replace assigning 0 with REG_NONE in both functions.
