nilfs2: reject invalid file types when reading inodes
commit 4aead50caf67e01020c8be1945c3201e8a972a27 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.
