There are some coding style issues, please use checkpatch.pl.

Back then I voted against "if (xen_enabled())" as I was planning for a
msi injection hook that also Xen could use. That may change again, the
final MSI layer design is not settled yet. Therefore, no concerns from
that POV, this work takes longer. We can refactor the Xen hooks during
that run again.

However, you know that you miss those (uncommon) messages that are
injected via DMA? They end up directly in apic_deliver_msi (where KVM
will once pick them up as well).
