[PATCH 1/3] LoongArch: KVM: Add stub for kvm_arch_vcpu_preempted_in_kernel

[Bibo Mao]

Since Pause-Loop Exiting is not supported by LoongArch hardware, nor
pv spinlock feature is not supported, function kvm_vcpu_on_spin() is
not used. Function kvm_arch_vcpu_preempted_in_kernel() is defined as
stub function here since it is only called by unused function
kvm_vcpu_on_spin().
