X86/irq: failed to assign vectors from CPU0

Msi or Msi-x interrupts assign vectors from a CPU while the number of CUPs is more than 8. __assign_irq_vector() is responsible for assigning vectors from low-numbered CPUs by default. If there are a lot of Msi or Msi-x interrupts, it will cause the low-numbered CPUs out of
