x86/iommu: Fix header comments regarding standard and _FINISH macros

The comment line regarding IOMMU_INIT and IOMMU_INIT_FINISH
macros is incorrect:

  "The standard vs the _FINISH differs in that the _FINISH variant
  will continue detecting other IOMMUs in the call list..."

It should be "..the *standard* variant will continue
detecting..."

Fix that. Also, make it readable while at it.
