KVM: arm64: Remove pointless check for changed init target

At any time there is only a single valid value for KVM_ARM_VCPU_INIT,
depending on the current CPU implementation. In all likelihood, this
will be the generic ARMv8 target.

Drop the pointless check for a changed target value between calls to
KVM_ARM_VCPU_INIT and instead rely on the check against
kvm_target_cpu().
