Hibernation (S4) is triggered in a guest when it recieves a sleep trigger from the hypervisor. When the guest resumes from this power state, it does not see the SleepEnabled bit. In otherwords, the sleep button is not enabled on waking from an S4 state. This causes subsequent invocation of sleep state to fail in the guest. Fix this problem by enabling the sleep button in ACPI legacy wake.
