iommu/irq_remapping: Fix the regression of hpet irq remapping
Commit 71054d8841b4 ("x86, hpet: Introduce x86_msi_ops.setup_hpet_msi")
introduced x86_msi_ops.setup_hpet_msi to setup hpet MSI irq
when irq remapping enabled. This caused a regression of
hpet MSI irq remapping.
Original code flow before commit 71054d8841b4:
hpet_setup_msi_irq()
arch_setup_hpet_msi()
setup_hpet_msi_remapped()
remap_ops->setup_hpet_msi()
alloc_irte()
msi_compose_msg()
hpet_msi_write()
...
Current code flow after commit 71054d8841b4:
hpet_setup_msi_irq()
x86_msi.setup_hpet_msi()
setup_hpet_msi_remapped()
intel_setup_hpet_msi()
alloc_irte()
Currently, we only call alloc_irte() for hpet MSI, but
do not composed and wrote its msg...
