[ Upstream commit 3952659a6108f77a0d062d8e8487bdbdaf52a66c ]
gb_pm_runtime_get_sync has increased the usage counter of the device here.
Forgetting to call gb_pm_runtime_put_noidle will result in usage counter
leak in the error branch of (gbcodec_hw_params and gbcodec_prepare). We
fixed it by adding it.
Fixes: c388ae7696992 ("greybus: audio: Update pm runtime support in dai_ops
callback")
