Peter Zijlstra 31d50c551e perf/x86/amd/uncore: Do not register a task ctx for uncore PMUs 
The new sanity check introduced by:

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

... triggered on the AMD uncore driver.

Uncore PMUs are per node, they cannot have per-task counters. Fix it.
