Kees Cook 4fb60b158a firmware_loader: EFI firmware loader must handle pre-allocated buffer
The EFI platform firmware fallback would clobber any pre-allocated
buffers. Instead, correctly refuse to reallocate when too small (as
already done in the sysfs fallback), or perform allocation normally
when needed.
