usb-storage: add new no_read_disc_info quirk

Browse source 
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.
