iommu/debug: Add mutex to make attach/detach thread safe
This mutex lock will help to synchronise the usage of iommu domain
structure which is getting used by multiple threads to perform
iommu attach and iommu detach in case of any error.
Without this change we are seeing page poisoning - write after free
when running stress tests using iommu-debug test cases.
