PCI: xgene-msi: Resend an MSI racing with itself on a different CPU
Since changing the affinity of an MSI really is about changing
the target address and that it isn't possible to mask an individual
MSI, it is completely possible for an interrupt to race with itself,
usually resulting in a lost interrupt.
Paper over the design blunder by informing the core code of this
sad state of affairs.
