init/Kconfig: Add SMP to the dependencies of QOS_SCHED

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5UPB0


CVE: NA

------------------------------------------------------------

After CONFIG_SMP is disabled during kernel compilation,
CONFIG_QOS_SCHED is not disabled.
As a result, the following error occurs:

kernel/sched/fair.c: In function ‘check_qos_cfs_rq’:
kernel/sched/fair.c:7324:4: error: implicit declaration of function
‘sched_idle_cpu’; did you mean ‘sched_idle_rq’?

 7790 |   rq->idle_stamp = 0;
      |       ^~~~~~~~~~
      |       idle_state

This is because the definitions of the corresponding functions
and variables depend on the SMP configuration.
So add SMP to the dependencies of QOS_SCHED.
