tdb2: don't cancel transactions on lock failures in tdb1 backend.
In TDB2, the user can override locking functions, so they may
deliberarely fail (eg. be non-blocking) expecting to retry.
For this reason, the TDB2 API requires the caller to cancel the
transaction if tdb_transaction_prepare_commit() fails.
