Essentially all this message indicates is the SR-IOV device was removed from the VM the FortiGate is running on. SR-IOV is a method to split a single PCIE network card into multiple, virtual network cards. It is common in cloud environments such as Azure. 
 
If encountering this message, it is necessary to reach out to the cloud provider to see why this PCIE device was removed from the FortiGate.
