ASoC: rockchip: Fix a reference count leak.
[ Upstream commit5.4-rM2-2.2.x-imx-squashedf141a42215
] Calling pm_runtime_get_sync increments the counter even in case of failure, causing incorrect ref count if pm_runtime_put is not called in error handling paths. Call pm_runtime_put if pm_runtime_get_sync fails. Fixes:fc05a5b222
