KVM: SEV: Disallow COPY_ENC_CONTEXT_FROM if target has created vCPUs
Reject COPY_ENC_CONTEXT_FROM if the destination VM has created vCPUs.
KVM relies on SEV activation to occur before vCPUs are created, e.g. to
set VMCB flags and intercepts correctly.
Fixes: 54526d1fd593 ("KVM: x86: Support KVM VMs sharing SEV context")
