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.
