net/mlx5e: Move RQs diagnose to a dedicated function

Move rx reporter RQs diagnose from mlx5e_rx_reporter_diagnose() to a
dedicated function. This change is a preparation for the following
series which extends diagnose output for the rx reporter. While at it,
also pass a mlx5e_priv pointer to
mlx5e_rx_reporter_diagnose_common_config() as this is the argument the
latter actually needs.
