USB: don't choose configs with no interfaces

commit 62f9cfa3ece58268b3e92ca59c23b175f86205aa upstream.

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.)
