macvtap: Fix getPhysfn to get the PF of a direct attach network interface

Browse Source 
This patch renames getPhysfn to getPhysfnDev and adds code to get the
Physical function and Virtual Function index of the direct attach linkdev (if
the direct attach interface is a SRIOV VF). The idea is to send the port
profile message to a PF if the direct attach interface is a SRIOV VF.
