KVM: SEV: Fall back to vmalloc for SEV-ES scratch area if necessary
Use kvzalloc() to allocate KVM's buffer for SEV-ES's GHCB scratch area so
that KVM falls back to __vmalloc() if physically contiguous memory isn't
available. The buffer is purely a KVM software construct, i.e. there's
no need for it to be physically contiguous.
