Zero limit is treated the same as no limit

[Kostja Osipov]

tarantool> insert into t0 values ('Osipov', 'Konstantin')
Insert OK, 1 row affected
tarantool> insert into t0 values ('Ivanov', 'Konstantin')
Insert OK, 1 row affected
tarantool> insert into t0 values ('Petrov', 'Konstantin')
Insert OK, 1 row affected
tarantool> select * from t0 where k0='Osipov'
Found 1 tuple:
['Osipov', 'Konstantin']
tarantool> select * from t0 where k0='Osipov' limit 0
Found 1 tuple:
['Osipov', 'Konstantin']
tarantool> select * from t0 where k1='Konstantin' limit 0
Found 3 tuples:
['Osipov', 'Konstantin']
['Ivanov', 'Konstantin']
['Petrov', 'Konstantin']
tarantool> select * from t0 where k1='Konstantin' limit 1
Found 1 tuple:
['Osipov', 'Konstantin']

Suggested fix:

Treat limit of 0 as "No tuples", not as "All tuples"
