[p4orch] Fix handlePortStatusChangeNotification status deserialize

[bratashX]

It's cherry-pick PR from master branch: #2111

What I did
Moved sai_deserialize_free_port_oper_status_ntf(count, port_oper_status); call outside the loop iterating port_oper_status array.

Why I did it
Calling sai_deserialize_free_port_oper_status_ntf(count, port_oper_status); in loop causes double-free.

Program terminated with signal SIGABRT, Aborted.
