hinic interfaces aren't getting predictable names

Bug description:
[Impact]
Interfaces associated with Huawei "hinic" PCI adapters will not be assigned
predictable names[*] and instead remain using the kernel names (e.g. eth0).
This can lead to races where the interface names are not the same on every
boot. For example, in a system with both 2-port hinic and 2-port igb devices,
the hinic interfaces would be eth0 & eth1 if the kernel finished probing hinic
before igb loaded. But if igb completes loading first, the hinic interfaces
would be eth2 & eth3.

[Test Case]
grep ^eth /proc/net/dev
[Fix]
There's an upstream fix that properly associates the hinic interfaces with
their PCI devices, providing udev with the info it needs to generate a
predictable name.
[Regression Risk]
The big regression risk here is with existing bionic installs w/ hinic
devices. They will be currently using "eth" names by default, and this change
will cause those names to change to "enP" names after upgrade. However, in only
certain configs are those "eth" names reliable (e.g. only NIC in the system is
a hinic plug-in card). It sucks to introduce such a change in a stable release
- but users will be bitten by this when they upgrade or transition to the HWE
kernel anyway if we don't.
