Fix code issue when SonicV2Connector.get() return None. (#13250)

Browse Source 
Fix code issue when SonicV2Connector.get() return None.

#### Why I did it
When database key does not exist, SonicV2Connector.get() will return None.
Code will break if not check return value.

#### How I did it
Check SonicV2Connector.get() return value before use it.

#### How to verify it
Pass all E2E test case.
