xfs: fix scrub stats file permissions
When the kernel is in lockdown mode, debugfs will only show files that
are world-readable and cannot be written, mmaped, or used with ioctl.
That more or less describes the scrub stats file, except that the
permissions are wrong -- they should be 0444, not 0644. You can't write
the stats file, so the 0200 makes no sense.
Meanwhile, the clear_stats file is only writable, but it got mode 0400
instead of 0200, which would make more sense.
Fix both files so that they make sense.
