When compiled without ENABLE_EFI, efi_stub_measured() was not defined, so compilation would fail. But it's not enough to add a stub that returns -EOPNOTSUPP. We call this function in various places and usually print the error at warning or error level, so we'd print a confusing message. We also can't add a stub that always returns 0, because then we'd print a message like "Kernel stub did not measure", which would be confusing too. Adding special handling for -EOPNOTSUPP in every caller is also unattractive. So instead efi_stub_measured() is reworked to log the warning or error internally, and such logging is removed from the callers, and a stub is added that logs a custom message.
