netxen: reduce stack usage of netxen_nic_flash_print
Don't need to keep a struct netxen_new_user_info on the stack when we only are interested in printing the serial_num. Change to only reading the serial_num. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
