- Rename em_print_link_status() to em_update_link_status(). - In em_attach() remove em_check_for_link(). Not needed here, since   already done in em_hardware_init(). - In em_attach() replace the printing block with call to   em_update_link_status(). - Remove modification of sc->link_state from em_hardware_init() and   from em_media_status(). This makes em_update_link_status() a   single point of change. Call em_update_link_status() where needed.
