Jan Kara 1b241aa840 udf: Detect incorrect directory size ...

commit fa65653e575fbd958bdf5fb9c4a71a324e39510d upstream.

Detect when a directory entry is (possibly partially) beyond directory
size and return EIO in that case since it means the filesystem is
corrupted. Otherwise directory operations can further corrupt the
directory and possibly also oops the kernel.
