hw_cntrs_hndl was intended to be generic enough to be connected with
different type of counters and not only mlx5_fc. However, i don't see
any coming feature are using this generic interface, so I'll remove.

It is a little bit problematic,
1. That RDMA_UAPI_PTR is declared in ib_user_ioctl_verbs.h, while
mlx5_ib_flow_counters_data in mlx5-abi.h.
2. Other similar __aligned_u64 needs to be updated in other mlx5-abi.h structures.
