[PATCH] fork-comment-fix: remove ambiguous question mark in CLONE_CHILD_CLEARTID comment

[Minu Jin]

The current comment "Clear TID on mm_release()?" ends with a question mark,
implying uncertainty about whether the TID is actually cleared in mm_release().

However, the code flow is deterministic.
When a task exits, mm_release() explicitly checks 'tsk->clear_child_tid' and clears.

Since this behavior is unambiguous,
remove the confusing question mark and rephrase the comment to clearly state that TID is cleared in mm_release().
