[PATCH] KVM: PPC: Book3S HV: Replace kvmppc_find_vcpu() with kvm_get_vcpu()

[Thomas Huth <thuth@redhat.com>]

Both functions are doing the same thing - looking up the struct
kvm_vcpu pointer for a given vCPU ID. So there's no need for the
kvmppc_find_vcpu() function, simply use the common function instead.
