UEFI Loader problems in CURRENT

[Toomas Soome]

If the hung/crash is after printout of bootorder, and the fix (at least in some cases) is about setting the boot device (with linux tools, but I’d assume the efi bootmanager setup would do the same), it means, we do get bad value from efi boot manager variables, and if the fbsd installer and/or boot program update does not include the variable setup, we can not rely on those values in loader. Or, we should have foolproof way to check the values - if we can trust them. 

Rgds,
Toomas
