Subject: [PATCH -next] sched: fix cid_lock kernel-doc warnings

Fix kernel-doc warnings for cid_lock and use_cid_lock.
These comments are not in kernel-doc format.

 on line 11496 - I thought it was a doc line
kernel/sched/core.c:11505: warning: Cannot understand  * @use_cid_lock: Select cid allocation behavior: lock-free vs spinlock.
 on line 11505 - I thought it was a doc line
