[Chassis][database][sonic-db-cli] Fix the instance database# start up failure on LC

[mlok-nokia]

Why I did it

On multiasic LC, instance database# failed to start due to the sonic-db-cli -n asic# PING failed. soinc-db-cli -n asic0 PING failed which results in the /usr/bin/database.sh wait forever in the postStartAction(). Fixes sonic-net/sonic-buildimage#18395

How I did it

On multiasic LC, sonic-db-cli -n asic0 PING has been fixed/changed by PR #797. But when execute "sonic-db-cli -n asic0 PING" command, it will fail to ping the CHASSIS_STATE_DB and CHASSIS_APP_DB in the database-chassis on the supervisor card. The existing code uses db_name to check against
"redis_chassis.server" identify if it is for database-chassis is wrong. This commit uses variable "host" instead of db_name. This will fix the issue.

How to verify it

1. Boot up the chassis, execuet " docker ps" to verify the instance database0 and database1 containers are up.
