Summary

iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping()

Original description

The description as published by the source.

In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping()

After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node
unconditionally allocated"). For tear down scenario, fn is only freed
after fail to allocate ir_domain, though it also should be freed in case
dmar_enable_qi returns error.

Besides free fn, irq_domain and ir_msi_domain need to be removed as well
if intel_setup_irq_remapping fails to enable queued invalidation.

Improve the rewinding path by add out_free_ir_domain and out_free_fwnode
lables per Baolu's suggestion.
