hypervisor: Fix AIA IMSIC attr calculation

Browse Source 
The IMSIC attr of RISC-V AIA is wrongly configured to start from 0, which
would error out with `os error 22` (invalid argument).

```console
Error booting VM: VmBoot(DeviceManager(CreateInterruptController(CreateAia(CreateVaia(Vaia error SetDeviceAttribute(SetDeviceAttribute(Invalid argument (os error 22))))))))
```

`riscv_imsic_attr_of` should shift `cpu_index` by 1 here to produce
correct IMSIC attr.
