wl1271: fix the inetdev notifier callback return values
The wl1271_dev_notify() was returning 0 or -ENODEV, when it should return NOTIFY_* instead. Now we use NOTIFY_DONE when we didn't handle the event or NOTIFY_OK when we have handled it. For inetdev notifications, it doesn't matter whether we use NOTIFY_DONE or NOTIFY_OK, because it ignores the return value of the call to blocking_notifier_call_chain(). But the notify.h header says that NOTIFY_DONE is "Don't care" and NOTIFY_OK is "Suits me", so that seems to be the right way to do it.
