SVN rev 193436 on 2009-06-04 14:13:06Z by rmacklem
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.
