When some failure occurrs in the flow_hw_create_ctrl_tables(), the
"rte_flow_error" should be set properly with all needed information.
Then the rte_errno and the "message" will reflect the actual failure.
This will also solve the crash when trying to access the "message".
Fixes: 1939eb6f660c ("net/mlx5: support flow port action with HWS")
Fixes: 483181f7b6dd ("net/mlx5: support device control of representor matching")
Fixes: ddb68e47331e ("net/mlx5: add extended metadata mode for HWS")
