[PATCH 17/46] kernel: Move prototype declaration to appropriate header file from kernel/stop_machine.c

Move prototype declaration to header file include/linux/sched.h from
kernel/stop_machine.c because they are used by more than one file.

This eliminates the following warning in kernel/sched/core.c:
kernel/sched/core.c:851:6: warning: no previous prototype for ‘sched_set_stop_task’ [-Wmissing-prototypes]
