Add quiet flag to CD I/O
* linux/src/drivers/block/ide-cd.c (cdrom_queue_packet_command): Add `quiet' parameter, copied into the request. (cdrom_decode_status): Do not print I/O error when `quiet' field of request is non-zero. (cdrom_end_request): Do not print sense results when `quiet' field of request is non-zero. (cdrom_check_status, cdrom_read_capacity, cdrom_read_tocentry): Pass 1 to `cdrom_queue_packet_command''s `quiet' parameter. (cdrom_lockdoor, cdrom_eject, cdrom_pause, cdrom_startstop, cdrom_read_subchannel, cdrom_mode_sense, cdrom_mode_select, cdrom_play_lba_range_1, cdrom_read_block, cdrom_load_unload, ide_cdrom_ioctl): Pass 0 to `cdrom_queue_packet_command''s `quiet' parameter.
