Eric Auger 4c80ba392b iommu: fix KASAN use-after-free in iommu_insert_resv_region 
In case the new region gets merged into another one, the nr list node is
freed.  Checking its type while completing the merge algorithm leads to
a use-after-free.  Use new->type instead.

Fixes: 4dbd258ff63e ("iommu: Revisit iommu_insert_resv_region() implementation")
