Cleanup: match xattr reader API closer to id table API
Instead of creating everything in the "create" function, cleanup and create/initialize stuff in a "load" function. This allows the xattr reader to be reset/re-used and adds the benefit of not having to lug around references to the super block, compressor and file (altough the later two are hidden inside the meta reader).
