[rndis] Ignore start-of-day RNDIS_INDICATE_STATUS_MSG with status 0x4…

…0020006 Windows Server 2012 R2 generates an RNDIS_INDICATE_STATUS_MSG with a status code of 0x4002006. This status code does not appear to be documented anywhere within the sphere of human knowledge. Explicitly ignore this status code in order to avoid unnecessarily cluttering the display when RNDIS debugging is enabled. Signed-off-by: Michael Brown <mcb30@ipxe.org>
