Log Message:
-----------
[cmap] Don't let unknown-format subtables recurse in __getattr__

CmapSubtable.__getattr__ retries after ensureDecompiled(), relying on it
clearing self.data to terminate. Keeping the data means any missing
attribute -- hasattr(subtable, "length"), say -- recurses until the stack
blows instead of raising AttributeError.
