[PATCH 3/4] intel_iommu: Tear down address spaces before IOMMU reset

[peterx]

From: Peter Xu <peterx@redhat.com>

No bug report for this, but logically tearing down of existing address
space should happen before reset of IOMMU state / registers, because the
current address spaces may still rely on those information.
