tdb: fix locking error
54a51839ea65aa788b18fce8de0ae4f9ba63e4e7 "Make tdb transaction lock
recursive (samba version)" was broken: I "cleaned it up" and prevented
it from ever unlocking.
To see the problem:
$ bin/tdbtorture -s 1248142523
tdb_brlock failed (fd=3) at offset 8 rw_type=1 lck_type=14 len=1
tdb_transaction_lock: failed to get transaction lock
tdb_transaction_start failed: Resource deadlock avoided
My testcase relied on the *count* being correct, which it was. Fixing that
now.
