genirq/irqdomain: Make sure all irq domain flags are distinct
This was noticed when printing debugfs for MSIs on my ARM64 server. The
new dstate IRQD_MSI_NOMASK_QUIRK came out surprisingly while it should only
be the x86 stuff for the time being...
The new MSI quirk flag uses the same bit as IRQ_DOMAIN_NAME_ALLOCATED which
is oddly defined as bit 6 for no good reason.
Switch it to the non used bit 1.
Fixes: 6f1a4891a592 ("x86/apic/msi: Plug non-maskable MSI affinity race")
