perf/x86/amd/uncore: Fix __percpu annotation

The __percpu annotation in struct amd_uncore is confusing Sparse:

  uncore.c:649:10: sparse: warning: incorrect type in initializer (different address spaces)
  uncore.c:649:10: sparse:    expected void const [noderef] __percpu *__vpp_verify
  uncore.c:649:10: sparse:    got union amd_uncore_info *

The reason is that the __percpu annotation sits between the '*'
dereferencing operator and the member name.

Move it before the dereferencing operator to cure this.
