hw/uefi: remove debug function
This was never meant to be present in production builds. It's a code
path not hit on a normal boot (OVMF wouldn't try variable updates which
are not allowed), so this went unnoticed.
Remove the function. If needed for debugging the git log is your
friend.
Fixes: CVE-2026-58582
