[PATCH 20/22] KVM: SVM: Rename SEV implemenations to conform to kvm_x86_ops hooks

[Sean Christopherson <seanjc@google.com>]

Rename svm_vm_copy_asid_from() and svm_vm_migrate_from() to conform to
the names used by kvm_x86_ops, and opportunistically use "sev" instead of
"svm" to more precisely identify the role of the hooks.

svm_vm_copy_asid_from() in particular was poorly named as the function
does much more than simply copy the ASID.

No functional change intended.
