USB: don't choose configs with no interfaces
This patch (as1372) fixes a bug in the routine that chooses the
default configuration to install when a new USB device is detected.
The algorithm is supposed to look for a config whose first interface
is for a non-vendor-specific class. But the way it's currently
written, it will also accept a config with no interfaces at all, which
is not very useful. (Believe it or not, such things do exist.)
