do not call slow my_timer_init() several times

Details

    Description

      my_thr_timer() call times() which is slow at least on my system. Maybe it's due to spectre mitigations, I don't know. Flame graph shows profiling data for empty test. Perfschema and InnoDB storage engines calls my_thr_timer() while both can actually use the one initialized by server.
