Peter Zijlstra 8482716b9d perf/x86/amd/iommu: Do not register a task ctx for uncore like PMUs 
The new sanity check introduced by:

  2665784850 ("perf/core: Verify we have a single perf_hw_context PMU")

... triggered on the AMD IOMMU driver.

IOMMUs are not per logical CPU, they cannot have per-task counters. Fix it.
