perf/core: Fix perf_event_enable_on_exec() timekeeping (again)
Where commit:
7fce250915ef ("perf: Fix scaling vs. perf_event_enable_on_exec()")
disabled the ctx-time a-priory, such that all events get enabled and
scheduled at the time point in time, there is one hole in that patch,
when no events do get enabled nothing re-enables the ctx-time.
