[conn_graph] Fix the fanout connection parsing error (#2780)

Description of PR
Fanout graph parsing was broken due to #2517
Following errors were seen while running pfcwd tests
E RunAnsibleModuleFail: run module conn_graph_facts failed, Ansible Results =>

E },
E "msg": "Did not find port for Ethernet23/1 in the ports based on hwsku 'Arista-7260CX3' for host str-7260cx3-acs-fan-05"
E }

How did you do it?
Parsing logic added in #2517 was for SONIC duts. Retained the old logic when dev type is FanoutLeaf

How did you verify/test it?
Ran one of the pfcwd tests and it passed
