ASoC: rockchip: Fix a reference count leak. 

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 ("ASoC: rockchip: add support for pdm controller")
