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

["Srivatsa S. Bhat" <srivatsa@xxxxxxxxxxxxx>]

From: "Srivatsa S. Bhat (VMware)" <srivatsa@xxxxxxxxxxxxx>

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.
