Patch removes the bogus flag introduced by upstream commit
eefdbec1. Old code had buffer length check
that new code tried to handle with URB_SHORT_NOT_OK flag. With USB debugging
enabled bogus flag caused usb_submit_urb fail.

Remove URB_SHORT_NOT_OK flag and add buffer length check to urb completion
handler.
