PM / Hibernate: hibernation_ops->leave should be checked too
Because hibernate calls hibernation_ops->leave() without checking whether hibernation_ops->leave is NULL or not, hiberantion_set_ops should WARN_ON if hibernation_ops->leave is NULL. This patch added one more condition to check hibernation_ops->leave.
