cc: Don't try set RenderPasses on active tree after losing context.

DelegatedRendererLayerImpl passes the frame from the pending to the
active tree, but relies on there being a child_id_ on the active
layer that is known to the ResourceProvider. If the context was lost
while the frame was in the pending tree, the frames resources are
released, but we try to tell the resource provider to use the
empty frame with an invalid child id.

When the context is lost and we drop the frame, also unset the bool
saying we have a frame to pass to the active tree.

Oh, can you add a DCHECK(child_id_) here?
