compress/mlx5: support 32-bit systems

In order to support 32-bit systems, the 8B doorbell write should be
done by 2 4B stores.

The order between the store is important, that's why memory barrier
should be used between them.

The doorbell address is shared between all the queues, that's why a lock
should wrap the 2 stores.
