perf/core: Fix missing static inline on perf_cgroup_switch()

It looks like a "static inline" has been missed in front
of the empty definition of perf_cgroup_switch() under
certain configurations.

Fixes the following sparse warning:

  kernel/events/core.c:1035:1: warning: symbol 'perf_cgroup_switch' was not declared. Should it be static?
