ALREADY IN INVENTORY message in --nic

[lgmu]

Hi,

I have a quick question regarding this:
https://github.com/bb-Ricardo/check_redfish/blob/main/cr_module/nic.py#L141

A customer of us uses the --nic mode on a Dell Inc. PowerEdge C6420

We get the following output:
ALREADY in INVENTORY: NIC.Mezzanine.3-1
ALREADY in INVENTORY: NIC.Mezzanine.3-1
ALREADY in INVENTORY: NIC.Mezzanine.3-1
ALREADY in INVENTORY: NIC.Mezzanine.3-2
ALREADY in INVENTORY: NIC.Mezzanine.3-2
ALREADY in INVENTORY: NIC.Mezzanine.3-2
[OK]: All network adapter (3) and ports (5) are in good condition

Is the "ALREADY in INVENTORY" really neccessary on stdout? Maybe it could only be printed in verbose. Or is this something they can avoid by configuring the device itself in a different way?
