Mux: what about using target for mux

[rurirei]

here introduces a new mapping key: target address for the mux session pool, as this blocking the requests has the same destination instead. a simple trick for the mux blocking all problematic.

func (p *IncrementalWorkerPicker) findAvailable(target) int {
	for idx, w := range p.workers {
		if !w.IsFull() && w.Equal(target) {
			return idx
		}
	}

	return -1
}
