ext4: protect journal inode's blocks using block_validity
commit 345c0dbf3a30872d9b204db96b5857cd00808cae upstream.
Add the blocks which belong to the journal inode to block_validity's
system zone so attempts to deallocate or overwrite the journal due a
corrupted file system where the journal blocks are also claimed by
another inode.
