Bug description:
  [Impact]
  This is a regression in shim 15.4 that causes a crash in shim when chainbooting.

  Also, the machine resets when you exit grub, rather than going back to
  the EFI shell when launched from it.

  [Test plan]

  Boot an Ubuntu hirsute image in Secure Boot mode. While this issue was
  originally seen while chainbooting in
  https://github.com/lxc/lxd/issues/8770 - it was shown to be also
  reproducible just by booting a hirsute instance.

  [Where problems could occur]
  In exiting shim, failure to boot, etc.
