Reviewed by Simon Fraser.
RemoteLayerWithRemoteRenderingBackingStoreCollection::markAllBackingStoreVolatileFromTimer
stops the volatility timer if the operation is successful, since there should
be no further backing stores to mark volatile.
This is an async operation though, and it's possible for
markBackingStoreVolatileAfterReachabilityChange to have been called in the
interim and there are now new backing stores that aren't yet volatile.
This change ensures that we reschedule the volatility timer if any
markBackingStoreVolatileAfterReachabilityChange don't succesfully mark the
relevant surfaces as volatile.
