Ryusuke Konishi 79663a15a1 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.
