ctdb: Fix a stuck cluster lock holder after a delayed leader bcast
If a delayed broadcast by a previous cluster lock holder arrives, the
new legitimate leader will accept this without questioning in
leader_handler(). Without this patch rec->leader will never be
overwritten, and because rec->pnn != rec->leader we'll also never send
out fresh leader broadcasts. And because we hold the cluster lock,
nobody else can step up.
Fix this in the next round of leader broadcast timeout.

winbind NDR operation for regression testing. There are two issues here:
The opnum for this winbind NDR operation has changed (as new calls have
been added to the interface), it is no longer 16 but now 17. Better try
to lookup the current opnum from the IDL.
As tdbtool always returns with success error code regardless of the
success of its command - in this case a delete key operation - the test
is simply not able to fail at all (patch following to fix tdbtool
itself).
