virt/coco/sev-guest: Check SEV_SNP attribute at probe time
commit d6fd48eff7506bb866a54e40369df8899f2078a9 upstream.
No need to check it on every ioctl. And yes, this is a common SEV driver
but it does only SNP-specific operations currently. This can be
revisited later, when more use cases appear.
No functional changes.
