Describe the bug

NetInventory Task returns wrong port numbers for connections and doesn't list all connections with Unifi-Switches.

Issues this causes:

• Phantom hubs are created in GLPI
• Phantom networks are created in GLPI

netinventory Only shows 2 of the 4 connected devices, and all on port 3, while nothing is actually connected on port.
See below.

To reproduce

1. glpi-netinventory --community [...] --host [...] snmp-walk.walk.txt
2. see wrong output inventory.xml.txt

Expected behavior

For all connections to be displayed and on the correct ports.
Here is a somewhat fixed xml, where I manually entered the connected MAC addresses where they belong. (Port 9 being the upstream port)
inventory_fixed.xml.txt
The correct port information can be found under SNMP node 1.3.6.1.2.1.17.4.3.1 or 1.3.6.1.2.1.17.7.1.2.2.1
