iommu: Fix static checker warning in iommu_insert_device_resv_regions

Browse source

In case the device reserved region list is void, the returned value
of iommu_insert_device_resv_regions is uninitialized. Let's return 0
in that case.

This fixes commit 6c65fb318e ("iommu: iommu_get_group_resv_regions").
