qlcnic: Implement ndo_get_phys_port_id for 82xx adapter

Each function driver instance uses the MAC address of the
lowest function belonging to that physical port as a unique
port identifier. This port identifier is read and cached in
driver during probe and provided to user space through
ndo_get_phys_port_id()
