[PATCH v2] KVM: Fix order passed to iommu_unmap

[Jan Kiszka <jan.kiszka@web.de>]

From: Jan Kiszka <jan.kiszka@siemens.com>

This is obviously a left-over from the the old interface taking the
size. Apparently a mostly harmless issue with the current iommu_unmap
implementation.

I think this one is even closer to the right order. :)
