nohz: Use enum code for tick stop failure tracing message
It makes nohz tracing more lightweight, standard and easier to parse.
Examples:
user_loop-2904 [007] d..1 517.701126: tick_stop: success=1 dependency=NONE
user_loop-2904 [007] dn.1 518.021181: tick_stop: success=0 dependency=SCHED
posix_timers-6142 [007] d..1 1739.027400: tick_stop: success=0 dependency=POSIX_TIMER
user_loop-5463 [007] dN.1 1185.931939: tick_stop: success=0 dependency=PERF_EVENTS
