Assert that backend is used or can be connected to

Browse Source 
The assertion that was added to RWSplitSession::handle_slave_is_target
failed when delayed_retry was enabled or when slave reconnection
occurred. In 2.3, targets returned by the target selection functions do
not need to be in use but they must be valid connection targets.
