Remove superfluous wake in dpmsinputeventfilter destruction
Workspace already makes sure to only dynamically delete the dpmsinputeventfilter if all screens are currently on. This line to wake all screens is therefore redundant.
It's problematic as it can cause a crash on final teardown when workspace is destroyed.
