2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Alex Williamson <alex.william...@redhat.com>
commit 2fe9723df8e45fd247782adea244a5e653c30bf4 upstream.
If we run out of domain_ids and fail iommu_attach_domain(), we
fall into domain_exit() without having setup enough of the
domain structure for this to do anything useful. In fact, it
typically runs off into the weeds walking the bogus domain->devices
list. Just free the domain.
