So if ms-nfs41-client uses WNNC_NET_RDR2SAMPLE, we don't have to handle
these shares when checking the WNNC_NET_MS_NFS provider.  While it would
be nice if the nfs v4 driver would use some other WNNC type, this is
at least helpful for handling WNNC_NET_MS_NFS shares, because they
have more than one quirk...
