[PATCH] rcu: include torture_sched_setaffinity() declaration

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The prototype for torture_sched_setaffinity() moved to a
different header, which needs to be included from update.c
to avoid this W=1 warning:

kernel/rcu/update.c:529:6: error: no previous prototype for 'torture_sched_setaffinity' [-Werror=missing-prototypes]
  529 | long torture_sched_setaffinity(pid_t pid, const struct cpumask *in_mask)

Fixes: 521ec59e5453e ("torture: Move rcutorture_sched_setaffinity() out of rcutorture")
