This patch includes the following changes
- removes some netlink functions which are now available in virnetdev.c
- Adds a vf argument to all port profile functions

For 802.1Qbh devices, the port profile calls can use a vf argument if
passed by the caller. If the vf argument is -1 it will try to derive the vf
if the device passed is a virtual function.

For 802.1Qbg devices, This patch introduces a null check for the device
argument because during port profile assignment on a hostdev, this argument
can be null. Stefan CC'ed for comments

I agree to the change per se since entering the function with a NULL parameter would be fatal, though I am wondering under what condition this can occur. I don't see this happening in the Associate call path for example.
