mlx5_handle_error_cqe() only dump the content of the CQE which is raw hex
data, and not straighforward for debug. Print WC status message when we
got CQE error and dump is need.
Here is an example of how the dmesg log looks like with this:
infiniband mlx5_0: mlx5_handle_error_cqe:333:(pid 0): WC error: 10, message: remote access error
infiniband mlx5_0: dump_cqe:272:(pid 0): dump error cqe
