ctdb-daemon: Make node inactive in the NODE_STOP control

Currently some of this is supported by a periodic check in the
recovery daemon's main_loop(), which notices the flag change, sets
recovery mode active and freezes databases.  If STOP_NODE returns
immediately then the associated recovery can complete and the node can
be continued before databases are actually frozen.

Instead, immediately do all of the things that make a node inactive.

RN: Stop "ctdb stop" from completing before freezing databases
