enhance: cancel context when emptyDir failed

[jiefenghuang]

1. change: add cancel when failed
2. hint: does not use wg.Wait because the function call stack is too deep and mayebe block somewhere. It involves context handling in many other functions, we will strengthen the context handling of other interfaces in the future.
