nilfs2: cleanup multi kmem_cache_{create,destroy} code
This cleanup patch gives several improvements:
- Moving all kmem_cache_{create_destroy} calls into one place, which removes
some small function calls, cleans up error check code and clarify the logic.
- Mark all initial code in __init section.
- Remove some very obvious comments.
- Adjust some declarations.
- Fix some space-tab issues.
