throttle: Check for pending requests in throttle_group_unregister_bs()
throttle_group_unregister_bs() removes a BlockDriverState from its throttling group and destroys the timers. This means that there must be no pending throttled requests at that point (because it would be impossible to complete them), so the caller has to drain them first. At the moment throttle_group_unregister_bs() is only called from bdrv_io_limits_disable(), which already takes care of draining the requests, so there's nothing to worry about, but this patch makes this invariant explicit in the documentation and adds the relevant assertions.
