classifier: Fix use of uninitialized value.
Coverity reports use of uninitialized value of cursor. This happens in cls_cursor_start(), when rule is false, cursor.subtable is uninitialized. CID 279324. Signed-off-by: William Tu <u9012063@gmail.com> Reviewed-by: Greg Rose <gvrose8192@gmail.com> Signed-off-by: Ilya Maximets <i.maximets@ovn.org>
