Joerg Roedel d28aa3c157 x86/boot/compressed/64: Check SEV encryption in the 32-bit boot-path ...

commit fef81c8626 upstream.

Check whether the hypervisor reported the correct C-bit when running
as an SEV guest. Using a wrong C-bit position could be used to leak
sensitive data from the guest to the hypervisor.
