When the number of online CPUs is less than 16, we found that it will fail
to allocate 32 MSI interrupts (including 16 affinity interrupts) after the
hisi_sas module is unloaded and then reloaded.

After analysis, it is found that a bug exists when the ITS releases
interrupt resources, and this patch set contains a bugfix patch and a patch
for appending debugging information.

  irqchip/gic-v3-its: don't set bitmap for LPI which user didn't
    allocate
  genirq/msi: add an error print when __irq_domain_alloc_irqs() failed
