Traceback is logged when the network node info is omitted in ml2_cisco.ini file

[Danny Choi]

When the Network node info is omitted in the ml2_conf.ini file, traceback is logged during stack.sh and when the first VM is launched.

Snippet of the local.conf:

#Nexus Switch
[ml2_mech_cisco_nexus:172.20.231.5]
qa5 = port-channel:1,port-channel:2
qa6 = port-channel:1
qa11 = port-channel:1
physnet = physnet1
ssh_port = 22
username = admin
password = CTO1234!
nve_src_intf = 2

NOTE: qa4 is the Network node connecting to port-channel 1
