[PATCH v3 3/3] PCI: tegra: Silence set affinity failed warning

[Marek Vasut <marek.vasut+renesas@mailbox.org>]

Use newly introduced MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity unset
and allows migrate_one_irq() code in cpuhotplug.c to exit right away, without
printing "IRQ...: set affinity failed(-22)" warning.

Remove .irq_set_affinity implementation which only return -EINVAL from this
controller driver.
