Rafael J. Wysocki c52fa70c79 ACPI / sleep: Drain outstanding events after disabling multiple GPEs ...

After multiple GPEs have been disabled at the low level in one go,
like when acpi_disable_all_gpes() is called, we should always drain
all of the outstanding events from them, or interesting races become
possible.

For this reason, call acpi_os_wait_events_complete() after
acpi_enable_all_wakeup_gpes() and acpi_disable_all_gpes() in
acpi_freeze_prepare() and acpi_power_off_prepare(), respectively.
