virtio-gpu: Make non-gl display updates work again when blob=true

Browse Source 
In the case where the console does not have gl capability, and
if blob is set to true, make sure that the display updates still
work. Commit e86a93f554 accidentally broke this by misplacing
the return statement (in resource_flush) causing the updates to
be silently ignored.
