nilfs2: convert ifile to use kmap_local
Convert deprecated kmap() and kmap_atomic() to use kmap_local for the
ifile metadata file used to manage disk inodes.
In some usages, calls to kmap_local and kunmap_local are split into
different helpers, but those usages can be safely changed to local thread
kmap.
