nilfs2: localize highmem mapping for checkpoint finalization within cpfile
Move the checkpoint finalization routine to the cpfile side, and make the
page mapping local and temporary. And use kmap_local instead of kmap to
access the checkpoint entry page when finalizing a checkpoint.
In this conversion, some of the information on the checkpoint entry being
rewritten is passed through the arguments of the newly added method
nilfs_cpfile_finalize_checkpoint().
