perf sched: Move curr_thread initialization to perf_sched__map()
The curr_thread is used only for the 'perf sched map'. Put initialization
in perf_sched__map() 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 15.526 MB perf.data (140095 samples) ]
