vkernel/intr: Pin vkernel "hardware interrupts" to CPU0
Due to the nondeterminsm of CPU to which SIGIO will be delivered,
we can't depend on "hardware interrupts" of vkernel always happen
on the registered CPU. We now pin the vkernel "hardware interrupts"
to CPU0, so the interrupt scheduling code could always know the
correct ithread to be scheduled.
