sched/core: Remove pointless printout in sched_show_task()

torvalds · Ingo Molnar · commit 8243d5597793 · 2016-11-03T07:31:34.000+01:00
In sched_show_task() we print out a useless hex number, not even a symbol, and there's a big question mark whether this even makes sense anyway, I suspect we should just remove it all.
