WMI: Cater for multiple events with same GUID
WMI data blocks can contain WMI events with the same GUID but with
different notifiy_ids, for example volume up/down hotkeys.
This patch enables a single event handler to be registered and
unregistered against all events with same GUID but different
notify_ids. Since an event handler is passed the notify_id of
an event it can can differentiate between the different events.
The patch also ensures we only register and unregister a device per
unique GUID.
