  Modified files:
    sys/kern             subr_trap.c 
  Log:
  Change the way we ensure td_ucred is NULL if DIAGNOSTIC is defined.
  Instead of caching the ucred reference, just go ahead and eat the
  decerement and increment of the refcount.  Now that Giant is pushed down
  into crfree(), we no longer have to get Giant in the common case.  In the
  case when we are actually free'ing the ucred, we would normally free it on
  the next kernel entry, so the cost there is not new, just in a different
  place.  This also removse td_cache_ucred from struct thread.  This is
  still only done #ifdef DIAGNOSTIC.
