This fixes two printing bugs in cpucontrol(1). First, the utility will now print "updating from rev X to rev Y", instead of incorrect "updating to revision X", where X is actually the old revision. This also matches what Intel updater prints. Second, the utility won't incorrectly warn that the update failed after reading the new revision post update.
