If the channel is in confirm mode, it is currently not possible to determine if a message has been nack'ed. By throwing an exception within the confirm callback, it is at least possible to react to it.

Return false is not needed to end the wait loop, [since the amqp ext checks for exceptions](https://github.com/php-amqp/php-amqp/blob/e58ac221e317c840ee06f7731e0dc76c7d6a431a/amqp_methods_handling.c#L249).
