renderer-native: Don't attempt to queue mode sets on non-onscreen views

Browse Source 
A view is only a 'CoglOnscreen' if it ends up on a CRTC, thus needs a
mode. Other views are for virtual monitors, and require no mode setting,
so exclude them from the pending mode set list.

This avoids a dead lock when we'll be waiting indefinitely for mode
setting on a virtual monitor.
