    LoongArch: KVM: Fix kvm_device leak in kvm_ipi_destroy()

    In kvm_ioctl_create_device(), kvm_device has allocated memory,
    kvm_device->destroy() seems to be supposed to free its kvm_device
    struct, but kvm_ipi_destroy() is not currently doing this, that
    would lead to a memory leak.

    So, fix it.
