perf: Fix __percpu annotation
With bcecd5a529c1 ("percpu: repurpose __percpu tag as a named address
space qualifier") the normal compilers start caring about the __percpu
annotation, as such f67d1ffd841f ("perf/core: Detach 'struct
perf_cpu_pmu_context' and 'struct pmu' lifetimes") needs a fixup.
Fixes: f67d1ffd841f ("perf/core: Detach 'struct perf_cpu_pmu_context' and 'struct pmu' lifetimes")
Fixes: bcecd5a529c1 ("percpu: repurpose __percpu tag as a named address space qualifier")
