* Fix parallel_reading_from_replicas with clickhouse-bechmark
Before it produces the following error:
$ clickhouse-benchmark --stacktrace -i1 --query "select * from remote('127.1', default.data_mt) limit 10" --allow_experimental_parallel_reading_from_replicas=1 --max_parallel_replicas=3
Loaded 1 queries.
Logical error: 'Coordinator for parallel reading from replicas is not initialized'.
Aborted (core dumped)
Since it uses the same code, i.e RemoteQueryExecutor ->
MultiplexedConnections, which enables coordinator if it was requested
from settings, but it should be done only for non-initial queries, i.e.
when server send connection to another server.

* Fix 02226_parallel_reading_from_replicas_benchmark for older shellcheck
By shellcheck 0.8 does not complains, while on CI shellcheck 0.7.0 and
it does complains [1]:
In 02226_parallel_reading_from_replicas_benchmark.sh line 17:
--allow_experimental_parallel_reading_from_replicas=1
^-- SC2191: The = here is literal. To assign by index, use ( [index]=value ) with no spaces. To keep as literal, quote it.
Did you mean:
"--allow_experimental_parallel_reading_from_replicas=1"
