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.
