hfs: fix namelength memory corruption

Fix a stack corruption caused by a corrupted hfs filesystem.  If the
catalog name length is corrupted the memcpy overwrites the catalog btree
structure.  Since the field is limited to HFS_NAMELEN bytes in the
structure and the file format, we throw an error if it is too long.
