When trying to enter a domain-idlestate, we may occasionally fail to enter the state, which is informed to us by psci_cpu_suspend_enter() returning an error-code. In these cases, our corresponding genpd->power_off() callback has already returned zero to indicate success, leading to getting in-correct domain-idlestate statistics in debugfs for the genpd in question. Let's fix this by making use of the new pm_genpd_inc_rejected() helper, as it allows us to correct the domain-idlestate statistics for this type of scenario.
