Ralph Boehme 25df582739 dbwrap_ctdb: treat empty records in ltdb as non-existing

When fetching records from remote ctdb nodes via ctdbd_parse() or in
db_ctdb_traverse(), we already check for tombstone records and skip
them. This was originally also done for the ltdb checks.

See also bug: https://bugzilla.samba.org/show_bug.cgi?id=10008
(commit 1cae59ce112ccb51b45357a52b902f80fce1eef1).

Commit 925625b52886d40b50fc631bad8bdc81970f7598 reverted part of the
patch of bug 10008 due to a deadlock it introduced.

This patch re-introduces the consistent treatment of empty records in
the ltdb but avoids the deadlock by correctly signalling
NT_STATUS_NOT_FOUND if an empty record is found authoritatively in
the ltdb and not calling ctdb in this case.
