iommu/vt-d: Correctly disable Intel IOMMU force on 

I made a mistake in commit bfd20f1. We should skip the force on with the
option enabled instead of vice versa. Not sure why this passed our
performance test, sorry.

Fixes: bfd20f1cc8 ('x86, iommu/vt-d: Add an option to disable Intel IOMMU force on')
