zha: Fix cluster class check in single-cluster device type (#14303)

zigpy now allows custom devices, which might mean that devices have cluster
objects which are not instances of the default, but may be instances of
sub-classes of the default. This fixes the check for finding single-cluster
device entities to handle sub-classes properly.
