A bug in the pre-release version of efi-lockdown patch* applied to Cosmic and
later kernels improperly results in EPERM failures for some debugfs files.

Fixes: a1ba65da9cea ("UBUNTU: SAUCE: (efi-lockdown) debugfs: Restrict debugfs when the kernel is locked down")

Upstream's version of this code never introduced the bug, so the fix patch
isn't upstream either.

The fix patch looks correct by inspection.
