ANDROID: KVM: arm64: Remove 'struct kvm_vcpu' from the KMI

Browse Source 
With the addition of 'struct pkvm_module_ops' to the Android-14 KMI, we
inadvertently exposing a number of internal KVM data structures via the
unused '__hyp_running_vcpu' member of 'struct kvm_cpu_context'.

Fix up the KMI by making this field a 'void *' for everybody other than
genksyms.
