description:
Fix KASSERT triggered when attaching opl at wss@isapnp.

Not really tested (no h/w), but this problem is exhibited by the
congruent code in acpi and pnpbios attachments.

wss has two attributes, "wss" and "audiobus", and this call didn't
specify an iattr for opl to attach to.  config_search_internal asserts
that when no iattr is specified, the parent should only have one.
