  Log:
  Add a new macro wrapper WITNESS_CHECK() around the witness_warn() function.
  The difference between WITNESS_CHECK() and WITNESS_WARN() is that
  WITNESS_CHECK() should be used in the places that the return value of
  witness_warn() is checked, whereas WITNESS_WARN() should be used in places
  where the return value is ignored.  Specifically, in a kernel without
  WITNESS enabled, WITNESS_WARN() evaluates to an empty string where as
  WITNESS_CHECK evaluates to 0.  I also updated the one place that was
  checking the return value of WITNESS_WARN() to use WITNESS_CHECK.
