Title: unset conn->noreply when it is not invalid in process_delete_command

in process_delete_command.

below command is invalid. because 0 is only allowed.
delete 1 noreply

but because of noreply, although it is not executed. error is not returned.
so I think it is necessary to send error message it is not executed.
