[rndis] Ignore start-of-day RNDIS_INDICATE_STATUS_MSG with status 0x40020006

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.
