usb-storage: add new no_read_disc_info quirk
Appotech ax3003 (the larger brother of the ax203) based devices are even more buggy then the ax203. They will go of into lala land when ever they see a READ_DISC_INFO scsi command. So add a new US_FL which tells the scsi sr driver to not issue any READ_DISC_INFO scsi commands.
