PCI: mediatek-gen3: Silence 'set affinity failed' warning 

JIRA: https://issues.redhat.com/browse/RHEL-67693
Upstream Status: 425c07563f4cefdb4d521d1f1cf5990004a388fa

commit 425c07563f4cefdb4d521d1f1cf5990004a388fa

    PCI: mediatek-gen3: Silence 'set affinity failed' warning

    Use MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity() unset and allows
    migrate_one_irq() to exit right away, without warnings like this:

      IRQ...: set affinity failed(-22)

    Remove the .irq_set_affinity() implementation that is no longer needed.
