Remove the limitation preventing adding a vport's MAC address to the
Multi-Physical Function Switch (MPFS) more than once per E-switch, as
there is no difference in the MPFS if an address is being used by an
E-switch more than once.
This allows the E-switch to have multiple vports with the same MAC
address, allowing vports to be classified by VLAN id instead of by MAC
if desired.
