Subject: [PATCH 44/46] kernel: Move prototype declaration to header file
 kernel/sched/sched.h from kernel/sched/rt.c

Move prototype declaration of function to header file
kernel/sched/sched.h from kernel/sched/rt.c because it is used by more
than one file.

This eliminates the following warning in kernel/sched/debug.c:
kernel/sched/debug.c:246:6: warning: no previous prototype for ‘print_rt_rq’ [-Wmissing-prototypes]
