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.

changed with v1:
- No need to print error log when the return value is -EAGAIN
