PCI: xilinx-xdma: Silence 'set affinity failed' warning

Browse Source 
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.
