reset active application code as 'N/A' when port shutdown

[chiourung]

Description

Motivation and Context

In the add_rack test, it would compare the TRANSCEIVER_INFO for two cases:
case 1. config reload (the admin status of Ethernet64 is down in config_db.json)
case 2. config reload (the admin status of Ethernet64 is up in config_db.json) and then shutdown Ethernet64

In case 1. it would not do CMIS init and the active application is 'N/A'.
In case 2. it would do CMIS init first and then disable TX. The active application would retain the value of the last CMIS init.
=> Modify the code to reset the active application on port shutdown to ensure that the active application would be the same for the above two cases.
