intel-iommu: iommu init error path bug fixes
The kcalloc() failure path in iommu_init_domains() calls
free_dmar_iommu(), which assumes that ->domains, ->domain_ids,
and ->lock have been properly initialized.
Add checks in free_[dmar]_iommu to not use ->domains,->domain_ids
if not alloced. Move the lock init to prior to the kcalloc()'s,
so it is valid in free_context_table() when free_dmar_iommu() invokes
it at the end.
Patch based on iommu-2.6,
commit 132032274a594ee9ffb6b9c9e2e9698149a09ea9
