Subject: [PATCH 2/2] s3: winbindd: Move calling setup_domain_child() into
 add_trusted_domain().

Ensure it only gets called when a new domain is allocated
and added to the list.

This should fix problems with the previous logic where
setup_domain_child() was called in places where an existing
domain was returned.
