with the introduction of CPU directed interrupts the kernel
parameter pci=force_floating was introduced to fall back
to the previous behavior using floating irqs.
However we were still setting the affinity in that case,
both in __irq_alloc_descs() and via the irq_set_affinity
callback in struct irq_chip.
For the former only set the affinity in the directed case.
The latter is explicitly set in zpci_directed_irq_init()
so we can just leave it unset for the floating case.
Fixes: e979ce7bced2 ("s390/pci: provide support for CPU directed interrupts")
