[ Upstream commit f7c4842abfa1a219554a3ffd8c317e8fdd979bec ]

snd_soc_dai_link_event() is updating snd_soc_dai :: active,
but it is unbalance.
It counts up if it has startup callback.

	case SND_SOC_DAPM_PRE_PMU:
		...
		snd_soc_dapm_widget_for_each_source_path(w, path) {
			...
			if (source->driver->ops->startup) {
				...
=>				source->active++;
			}
			...
		}
		...

But, always counts down

	case SND_SOC_DAPM_PRE_PMD:
		...
		snd_soc_dapm_widget_for_each_source_path(w, path) {
			...
=>			source->active--;
			...
		}

This patch always counts up when SND_SOC_DAPM_PRE_PMD.
