compress/mlx5: support partial transformation

Browse Source 
Currently compress, decompress and dma are allowed
only when all 3 capabilities are on.
A case where the user wants decompress offload, if
decompress capability is on but one of compress,
dma is off, is not allowed.
Split compress/decompress/dma support check to allow
partial transformations.
