[action] [PR:4229] Fix dump port state CLI command crash on multi-asic platforms

[mssonicbld]

What I did

Currently sudo dump state -d APPL_DB -n asic0 port Ethernet16 CLI command crashes on multi-asic platforms.

The error occurs because the code checks if any database configuration is initialized and loaded which is falsy value on multi-asic system. This results in following runtime error:

RuntimeError: :- validateNamespace: Initialize global DB config using API SonicDBConfig::initializeGlobalConfig.

The multi-ASIC platforms specifically needs the global database configuration to be initialized. The pull request fixes the condition on loading expected database configuration based on single or multi-asic system.

How I did it

Fixed it by using isGlobalInit() check for multi-asic and isInit() for single-asic to ensure the correct DB configuration is loaded before creating connectors.

How to verify it

Verified on single and multi-asic linecard. After fix, dump port state command no longer result in a crash and returns the expected results.

Previous command output (if the output of a command-line utility has changed)

New command output (if the output of a command-line utility has changed)

Command output after fix
