The issue is that not all errors should result in failure.

That code tries to remove ACL from a directory, and there are several cases:

1) success: that's good obviously
2) error: no ACL was found: that's also good
3) error: ACL's are not supported by the filesystem: this is also good
4) error: ACL was there but we failed to remove it for some other
reason: this is not good

The patch adds handling of case 3.

Thanks,
Miklos
