media: mediatek: vcodec: Using pm_runtime_put instead of pm_runtime_put_sync

pm_runtime_put will set RPM_ASYNC flag then queue an idle-notification
request again, won't return error immediately until current request is
scheduled.

But pm_runtime_put_sync run the ->runtime_idle() callback directly, return
error immediately no matter whether current request is scheduled.
