Ryusuke Konishi 4aead50caf nilfs2: reject invalid file types when reading inodes ...

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.
