intel_iommu, amd_iommu: allow UNMAP notifiers
x86 vIOMMUs still lack of a complete IOMMU notifier mechanism.
Before that is achieved, let's open a door for vhost DMAR support,
which only requires cache invalidations (UNMAP operations).
Meanwhile, convert hw_error() to error_report() and exit(1), to make
the error messages cleaner and obvious (no CPU registers will be dumped).
