x86/vtd: Drop struct qi_ctrl

It is unclear why this abstraction exists, but iommu_qi_ctrl() returns
possibly NULL and every user unconditionally dereferences the result.  In
practice, I can't spot a path where iommu is NULL, so I think it is mostly
dead.

Move the sole member into struct vtd_iommu, and delete iommu_qi_ctrl().
