sched/numa: Move task_numa_free() to __put_task_struct()
Bad idea on -rt:
[ 908.026136] [<ffffffff8150ad6a>] rt_spin_lock_slowlock+0xaa/0x2c0
[ 908.026145] [<ffffffff8108f701>] task_numa_free+0x31/0x130

[ 908.026170] [<ffffffff810658cf>] get_signal_to_deliver+0xaf/0x680

[ 908.026186] [<ffffffff81513176>] int_signal+0x12/0x17
[ 908.026193] [<00007ff2a388b1d0>] 0x7ff2a388b1cf
and since upstream does not mind where we do this, be a bit nicer ...
