bug in check for vmx instances

[kamatsuoka]

This line clearly has a logic problem:

quickstart-cisco-meraki-sd-wan-vmx/functions/source/lambda_function.py

Line 209 in 510a621

if ec2_vmx1_id and ec2_vmx1_id and meraki_vmx1_id and meraki_vmx1_id:

Should it be

if (ec2_vmx1_id and meraki_vmx1_id) or (ec2_vmx2_id and meraki_vmx2_id):

to check that at least one vmx has both an ec2 and a meraki id?
