kernel - Deal with lost IPIs (VM related) (2)

* Fix an issue where Xinvltlb interacts badly with a drm console framebuffer,
  imploding the machine.  The 1/16 second watchdog can trigger during certain
  DRM operations due to excessive interrupt disablement in the linux DRM code.

* Avoid kprintf()ing anything by default.

* Also make a minor fix to the watchdog logic to force the higher-level
  Xinvltlb loop to re-test.
