x86: KVM: SVM: use kvm_lock_all_vcpus instead of a custom implementation

Browse source

Use kvm_lock_all_vcpus instead of sev's own implementation.

Because kvm_lock_all_vcpus uses the _nest_lock feature of lockdep, which
ignores subclasses, there is no longer a need to use separate subclasses
for source and target VMs.

No functional change intended.
