USB: accept RNDIS configs if there's no alternative
USB: accept RNDIS configs if there's no alternative

This patch (as1410) makes a slight change to the strategy used for
choosing a default configuration.  Currently we skip configs whose
first interface is RNDIS, if the kernel wasn't built with the
corresponding driver.  This risks losing access to the other
interfaces in those configs.  In addition, if there is only one config
then we will end up not configuring the device at all.

This changes the logic; now such configurations will be skipped only
if there is at least one other config.
