virt: sev-guest: Contain snp_guest_request_ioctl in sev-guest
SNP Guest Request uses only exitinfo2 which is a return value from GHCB, has
meaning beyond ioctl and therefore belongs to struct snp_guest_req.
Move exitinfo2 there and remove snp_guest_request_ioctl from the SEV platform
code.
No functional change intended.
