[PATCH] perf/core: update outdated comment for refactored ctx_flexible_sched_in()

[Kexin Sun]

ctx_flexible_sched_in() was split into pmu_groups_sched_in()
for scheduling a single PMU's event groups and ctx_groups_sched_in()
for iterating over PMU contexts by commit f06cc667f799 ("perf:
Optimize perf_cgroup_switch()").  ctx_groups_sched_in() was then
folded into __pmu_ctx_sched_in() by commit 2d17cf1abcbe ("perf:
Optimize context reschedule for single PMU cases").

__pmu_ctx_sched_in() is now the function that schedules flexible
events and may re-set rotate_necessary. Update the references to
ctx_flexible_sched_in() accordingly.
