PM / Domains: Fix link checking when add subdomain
Current pm_genpd_add_subdomain() will allow duplicated link between master and slave domain. This patch fixed it. Because when current pm_genpd_add_subdomain() checks whether the link between the master and slave generic PM domain already exists, slave_links instead of master_links of master domain is used.
