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.
