Kees Cook 8a28452465 firmware_loader: EFI firmware loader must handle pre-allocated buffer ...

commit 4fb60b158a upstream.

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.

Fixes: e4c2c0ff00 ("firmware: Add new platform fallback mechanism and firmware_request_platform()")
