Fix two races in the server side krpc w.r.t upcalls:
  Add a flag so that soupcall_clear() is only called once to cancel
  an upcall.
  Move the test for xprt_registered in the upcall down to after the
  mtx_lock() of the pool mutex, to catch the case where it is
  unregistered while the upcall is waiting for the mutex.
Also, move the mtx_destroy() of the pool mutex to after SVC_RELEASE(),
so that it isn't destroyed before the upcalls are disabled.
