x86/smpboot: Remove a stray comment about CPU hotplug

Browse source 
This old comment is irrelavant to the logic of disabling interrupts and
could be misleading. Remove it.

Now, hlt_play_dead() resembles the code that the comment was initially
added for, but, it doesn't make sense anymore because an offlined cpu
could also be put into other states such as mwait.
