[tarantool-patches] [PATCH v2 1/4] sql: don't increment row count on FK creation within CREATE TABLE

[Nikita Pettik <korablev@tarantool.org>]

We have agreement that each successful DDL operation returns 1 (one) as
a row count (via IProto protocol or changes() SQL function), despite
the number of other created objects (e.g. indexes, sequences, FK
constraints etc).

Needed for #2181
