[PATCH 5.14 085/334] ASoC: mediatek: mt8183: Fix Unbalanced pm_runtime_enable in mt8183_afe_pcm_dev_probe

From: Zhang Qilong <zhangqilong3@huawei.com>

[ Upstream commit 19f479c37f76e926a6c0bec974a4d09826e32fc6 ]

Add missing pm_runtime_disable() when probe error out. It could
avoid pm_runtime implementation complains when removing and probing
again the driver.

Fixes:a94aec035a122 ("ASoC: mediatek: mt8183: add platform driver")
