ASoC: rockchip: Fix a reference count leak.
[ Upstream commit f141a422159a199f4c8dedb7e0df55b3b2cf16cd ]
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: fc05a5b22253 ("ASoC: rockchip: add support for pdm controller")
