[PATCH master 00/39] efi: fix bugs

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

While adding new tests for the barebox EFI support, a number of issues
were unearthed. Additionally, I ran Claude Code to determine suspicious
looking patterns and it found a number of extra issues, mostly in error
paths.

Except for patches 36, 37 and 38, all other patches affect only efi/,
so I hope it's ok to merge into master after review.
