Guests may not actually ENABLE_QUEUES until they get configured, and thus between driver load and device configuration the VF may show inaccurate link status. Fix this by also sending the link state after GET_VF_RESOURCES. Although we could remove the message following ENABLE_QUEUES, it's not that significant of a loss, so this patch just keeps both to ensure maximum compatibility with guests on various OSes. Specifically, without this patch guests running FreeBSD will display inaccurate link state until the device is brought up. This is mostly a cosmetic issue but can be confusing to system administrators.
