ide: add ide_atapi_{discard_data,write_zeros} inline helpers
Add ide_atapi_{discard_data,write_zeros} inline helpers to <linux/ide.h> and use them instead of home-brewn helpers in ide-{floppy,tape,scsi}. There should be no functional changes caused by this patch. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
