Tom Lendacky eb65f96cb3 virt: sev-guest: Choose the VMPCK key based on executing VMPL ...

Currently, the sev-guest driver uses the vmpck-0 key by default. When an
SVSM is present, the kernel is running at a VMPL other than 0 and the
vmpck-0 key is no longer available. If a specific vmpck key has not be
requested by the user via the vmpck_id module parameter, choose the
vmpck key based on the active VMPL level.
