Disable transparent hugepages

I stumbled upon this feature when some Windows VMs running 3D accelerated programs exhibited freezes of multiple seconds every now and then. We quickly discovered khugepaged would hog the CPU completely during these hangs. Disabling THP solved any performance issues.

<on-the-clock>Do you mind opening a support ticket for this with VMware? You can't be the only person seeing this, and it'd be great for us to check for this specifically when dealing with mystery-meat "bad perf in XYZ VM" bugs.</on-the-clock>
