[PATCH] USB: Don't ask for string descriptor lengths

Okay, here's a revised patch (as332b).  This tries first to ask for 255
bytes, and if that fails then it asks for the length and the full
descriptor.  Hopefully nobody will object to applying this version...

You know, it occurs to me that the have_langid field in usb_device could
easily be eliminated.  Just set string_langid to -1 during initialization
and test for whether or not it is >= 0.  I'll do that some other time.
