renderer/native: Don't queue mode set on hotplug power-save on

Browse Source 
We need to trigger a mode set when power-save changes to 'on' if it's
purely about power saving, but when they arrive as part of a hotplug
event, we'll handle all that later, in the monitors-changed handling,
that contains the new configuration.

This avoids a crash that happens due to the mode set being queued on now
disabled connectors.
