btrfs: compression: attach workspace manager to the ops
There's a lot of indirection when the generic code calls into algo-specific callbacks to reach the private workspace manager structure and back to the generic code. To simplify that, export the workspace manager for heuristic, LZO and ZLIB, while ZSTD is going to use it's own manager.
