platform/x86: wmi: Return immediately if an suitable WMI event is found

Commit 58f6425eb92f ("WMI: Cater for multiple events with same GUID")
allowed legacy WMI notify handlers to be installed for multiple WMI
devices with the same GUID.
However this is useless since the legacy GUID-based interface is
blacklisted from seeing WMI devices with duplicated GUIDs.

Return immediately if a suitable WMI event is found in
wmi_install/remove_notify_handler() since searching for other suitable
events is pointless.

Tested on a Dell Inspiron 3505 and a Acer Aspire E1-731.
