Remove FLAG_LINK_INTR because otherwiese usbnet.c will set the curruent link
state to down during initialization. Currently we do not support link-state
changes for SMSC95XX because the driver uses mdio/phy/irqchip infrastructure
that is hard to enable. Therefore, the driver must be started with NIC whose
link is up.
