x86: Fix mwait_play_dead() faulting on mwait-incapable cpus
A logic error in mwait_play_dead() causes the kernel to use
mwait even on cpus which don't support it, such as KVM virtual
cpus.
Introduced by:
349c004e3d31: x86: A fast way to check capabilities of the current cpu
Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=36222
