bozo: avoid canceling the sigkill timer for hung processes

A sigkill signal is sent to fileserver processes when a timeout is
exceeded for shutting down processes for the fs/dafs bnode.
(Currently 30 minutes for the fileserver, 1 minute for the other
server processes.)

If the bnode goal is set to run before this timeout expires, the
timer is incorrectly stopped, and a wedged process is never killed.
Fix this by not canceling the timer when a fs/dafs process has been
signaled to shutdown, regardless of the current goal.
