perf sched: Move start_work_mutex and work_done_wait_mutex initialization to perf_sched__replay()
The start_work_mutex and work_done_wait_mutex are used only for the
'perf sched replay'. Put their initialization in perf_sched__replay () to
reduce unnecessary actions in other commands.
Simple functional testing:
# perf sched record perf bench sched messaging
# Running 'sched/messaging' benchmark:
# 20 sender and receiver processes per group
# 10 groups == 400 processes run
Total time: 0.197 [sec]
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 14.952 MB perf.data (134165 samples) ]
