ls: fix panic when file removed too quickly

Fixes #5371

This seems like a good solution! If the file disappeared there's not much we can do anymore except just print it as we first got it. Could you add a comment in there explaining why this is necessary?

Also, I guess a test for this would be very unreliable right? Or do you have a reliable way to test this? If you do, it'd be great if you could add that to the test suite.

Comment added.

Testing this seems impossible with the actual test tool, we need fine control on process to suspend it quickly.
