Prevent ET8001-2FR4 do a CMIS reinit even only with the alias name set

[chiourung]

Description

When breakout ET8001-2FR4 to 2x400G, and configstates would be ConfigSuccess for 4 lanes and ConfigUndefined for the others.

When execute the api "api.scs_apply_datapath_init(host_lanes_mask)" for 0xf0,
the config status of lanes 1...4 would be ConfigUndefined and the config status of lanes 5...8 would be ConfigSuccess.
If the config state is ConfigUndefined, then it would do CMIS reinit for any set in the CONFIG_DB PORT table.
If the config state is ConfigUndefined, then it would do CMIS reinit when restart pmon.

Motivation and Context

In is_cmis_application_update_required, it check if the application is the same and if datapath is DataPathActivated.
It would not happen that the state of the config is fail, but the dataptach is activated.
I think skip CMIS int when config state is ConfigUndefined is saved.
