Peter Zijlstra 2cdbfd6567 perf/core: Fix endless multiplex timer 
commit 90c91dfb86 upstream.

Kan and Andi reported that we fail to kill rotation when the flexible
events go empty, but the context does not. XXX moar

Fixes: fd7d55172d ("perf/cgroups: Don't rotate events for cgroups unnecessarily")
