kernel - Disable the read_shortcut feature by default in -release

* Disable the read_shortcut feature by default in -release.  It is fairly
  stable but there are currently two reports of deadlocks under heavy loads
  that have not been resolved.

  So for now the feature is disabled by default.  It can be enabled anytime
  via its sysctl on 64-bit machines for people who want to run with it
  anyway.
