LoongArch: KVM: Use kvm_get_vcpu_by_id() instead of kvm_get_vcpu()

Browse Source 
Since using kvm_get_vcpu() may fail to retrieve the vCPU context,
kvm_get_vcpu_by_id() should be used instead.

Fixes: 8e3054261b ("LoongArch: KVM: Add IPI user mode read and write function")
Fixes: 3956a52bc0 ("LoongArch: KVM: Add EIOINTC read and write functions")
