fix: Call enable_deployer_ifc.yml in passive mode
fix: Call enable_deployer_ifc.yml in passive mode

Tasks to enable deployer NIC interface were moved from
'playbooks/enable_mgmt_switch.yml' to a new playbook
'playbooks/playbooks/enable_deployer_ifc.yml' in 79495a3. A call to the
new playbook was not added to the 'deploy-passive-1' function in
'scripts/gen_functions' preventing passive mode from properly setting up
deployer bridges.
