Subject: [PATCH RESEND -next] torture: avoid build error without CONFIG_RCU_TORTURE_TEST

If TORTURE_TEST=y(selected by TORTURE_LOCK_TEST) and RCU_TORTURE_TEST=n,
the following error is seen while building kernel/torture.c

kernel/torture.c: In function torture_onoff:
kernel/torture.c:239:3: error: implicit declaration of function
rcutorture_sched_setaffinity; did you mean __NR_ia32_sched_setaffinity?
[-Werror=implicit-function-declaration]
   rcutorture_sched_setaffinity(current->pid, cpumask_of(0));

Using sched_setaffnity() instead of rcutorture_sched_setaffinity() to
avoid the error.
