sched/s390: Fix compile error in sched/core.c
Commit 029632fbb7b7c9d85063cc9eb470de6c54873df3 ("sched: Make
separate sched*.c translation units") removed the include of
asm/mutex.h from sched.c.
This breaks the combination of:
CONFIG_MUTEX_SPIN_ON_OWNER=yes
CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX=yes
like s390 without mutex debugging:
CC kernel/sched/core.o
kernel/sched/core.c: In function ‘mutex_spin_on_owner’:
kernel/sched/core.c:3287: error: implicit declaration of function ‘arch_mutex_cpu_relax’
Lets re-add the include to kernel/sched/core.c
