IB/mlx5: Report mlx5 CQE compression caps during query
The capabilities include:
- Max number of compressed and aggregated CQEs in a single session,
while zero means unsupported.
- For Responder, there are two formats of mini CQE: mini CQE with Rx
hash and mini CQE with checksum. They're mutual exclusive.
