Ryusuke Konishi 1a5c204e17 nilfs2: reject invalid file types when reading inodes 
commit 4aead50caf upstream.

To prevent inodes with invalid file types from tripping through the vfs
and causing malfunctions or assertion failures, add a missing sanity check
when reading an inode from a block device.  If the file type is not valid,
treat it as a filesystem error.
