fs: add field to superblock to support cleancache
This second patch of eight in this cleancache series adds a field to
the generic superblock to squirrel away a pool identifier that is
dynamically provided by cleancache-enabled filesystems at mount time
to uniquely identify files and pages belonging to this mounted filesystem.
Details and a FAQ can be found in Documentation/vm/cleancache.txt
