Don't loop forever in load_certs() with buggy firmware
On DELL R350 booting DVD through RFS with BIOS 1.4.2 in Secure Boot,
firmware returns EFI_BUFFER_TOO_SMALL but with new buffersize set to 0,
which causes the load_certs() code to loop forever:
while (1) {
efi_status = dir->Read(dir, &buffersize, buffer);
if (efi_status == EFI_BUFFER_TOO_SMALL) {
...
continue;
}
...
}
This commit prevents such infinite loop.
