Coverity report for EFI subsystem

Hi Tom,

Heinirch forwarded me a coverity report a few days ago regarding some changes in the EFI subsystem and specifically the protocol management functions.

The issues reported were: - CID 376213 - CID 376206 - CID 376203 - CID 376200 - CID 376199 - CID 376195

The last one has been already fixed here [0] and you should get a pull request soon. The rest should be marked as false positives. We are initializing the va_args outside the reported functions and I think coverity gets confused. If someone thinks otherwise please shout
