nilfs2: always set back pointer to host inode in mapping->host
In the current nilfs, page cache for btree nodes and meta data files
do not set a valid back pointer to the host inode in mapping->host.
This will change it so that every address space in nilfs uses
mapping->host to hold its host inode.
