PM: domains: Drop genpd status manipulation for hibernate restore
The genpd status manipulation for hibernate restore has really never worked as intended. For example, if the genpd->status was GENPD_STATE_ON, the parent domain's `sd_count` must have been increased, so it needs to be adjusted too. So drop this status manipulation.
