[PATCH] net: forcedeth call restore mac addr in nv_shutdown patch

| [netdrvr] forcedeth: setup wake-on-lan before shutting down
|
| When hibernating in 'shutdown' mode, after saving the image the suspend hook
| is not called again.
| However, if the device is in promiscous mode, wake-on-lan will not work.
| This adds a shutdown hook to setup wake-on-lan before the final shutdown.

my servers with nvidia ck804 and mcp55 will reverse mac address with kexec.
it turns out need to restore mac addr in nv_shutdown.
