Import three fixes from my local GitHub repository:
- Don't attempt to remove Vcb from list twice on shutdown
- Properly add CCB to root_file
- Init cache for root_file so that cache uninit on shutdown isn't problematic

This fixes BTRFS in ReactOS.
These fixes have already been submitted upstream (https://github.com/maharmstone/btrfs/pull/23).
