Automatic merge from submit-queue refactor DeviceOpened() so it won't return error if device doesn't exist <!-- Thanks for sending a pull request! Here are some tips for you: 1.

Some volumes such as rbd don't support 3rd party detach, they have to be detached during unmount. Once detached, the device path vanishes. This causes false alarm when DeviceOpened() is called. The fix is to ignore error IsNotExist **Which issue this PR fixes** _(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)_: fixes # **Special notes for your reviewer**: @kubernetes/sig-storage **Release note**: <!-- Steps to write your release note: 1.
