Subject: [PATCH 55/58] sched: Add prototype for sched_set_stop_task

kernel/sched/core.c defines a function sched_set_stop_task, only
referenced from kernel/stop_machine.c via an extern declaration; no
header file defines a prototype for sched_set_stop_task.  Add a
prototype right before its definition, to satisfy GCC
(-Wmissing-prototypes) and Sparse (-Wdecl).

kernel/sched/core.c:803:6: warning: no previous prototype for ‘sched_set_stop_task’ [-Wmissing-prototypes]
