logical-monitor: Don't set the CRTC logical monitor if not assigned

Browse Source 
When adding a monitor and all its outputs, don't try to set the logical
monitor of the outputs CRTC if none was assigned. This might happen if
a tiled monitor only uses a subset of the connectors it are connected
via.
