LoongArch: KVM: Set vcpu->cpu before IN_GUEST_MODE is set

Browse source

In function kvm_make_vcpu_request(), it will send IPI to physical CPU
when vCPU is in IN_GUEST_MODE mode. And physical CPU is set in function
kvm_check_vpid(), thus it should be called before IN_GUEST_MODE is set.
Otherwise IPI will send to wrong old physical CPU where vCPU is running.
