  Remove an assertion that is no longer correct with the addition of
  sx_sleep().  During sx_sleep(), we drop the sleepqueue chain lock after
  putting the thread on the queue but before checking for signals while
  we release the sx lock.  If another thread wakes up the thread that is
  about to go to sleep during that window, then TDF_SINTR won't be set when
  the current thread checks for signals.  Thus, it isn't accurate to always
  assert that that flag is set here anymore.
