Subject: [PATCH] x86/hotplug: Remove incorrect comment about mwait_play_dead()

The comment that says mwait_play_dead() returns only on failure is a bit
misleading because mwait_play_dead() could actually return for valid
reasons (such as mwait not being supported by the platform) that do not
indicate a failure of the CPU offline operation. So, remove the comment.
