udev: mark the SRIO-V functions as unamanged by NetworkManager

From https://bugzilla.redhat.com/show_bug.cgi?id=1720157:

Accelerated Networking on Azure exposes a new SRIOV interface to the VM.
This interface is transparently bonded to the synthetic interface,
so NetworkManager should just ignore any SRIOV interfaces.

The rule is originally from Haiyang Zhang <haiyangz@microsoft.com>.
