Since commit 5fe71d271d ("irqchip/gic-v3-its: Tag ITS device as shared if
allocating for a proxy device"), some of the devices are wrongly marked as
"shared" by the ITS driver on systems equipped with the ITS(es). The
problem is that the @info->flags may not be initialized anywhere and we end
up looking at random bits on the stack. That's obviously not good.
We can perform the initialization in the IRQ core layer before calling
msi_domain_prepare_irqs(), which is neat enough.
