[Chassis][multiasic] Fix the sonic-db-cli core files issue on multiasic platform after the c++ implementation of sonic-db-cli (#13207)

Fixe #12047. After the c++ implementation of the sonic-db-cli, sonic-db-cli PING command tries to initialize the global database for all instances database starting. If all instance database-config.json are not ready yet. it will crash and generate core file. PR sonic-net/sonic-swss-common#701 only fix the crash and the process abortion.
