Virtual NIC miss sequence on guest OS which created by an imported template

Issue

• When a virtual guest with multiple nics is created by template which imported from other Datacenter, the sequence of virtual nics will be wrong.
• Create a virtual guest on DataCenter-1 which have multiple virtual nics. The sequence of virtual nics such as below:

Nic1 = rhevm = eth0
Nic2 = br2 = eth1
Nic3 = br3 = eth2
Nic4 = br4 = eth3

• Make a template out of it and export to export domain.
• Import the template to Datacenter-2.
• Create virtual guest with the imported template on Datacenter-2.
• The nics will lose sequence:

Nic1 = rhevm = eth3
Nic2 = br2 = eth0
Nic3 = br3 = eth1
Nic4 = br4 = eth2

• Which can be reproduced every time.
