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.
