libata: kill qc->nsect and cursect
libata used two separate sets of variables to record request size and current offset for ATA and ATAPI. This is confusing and fragile. This patch replaces qc->nsect/cursect with qc->nbytes/curbytes and kills them. Also, ata_pio_sector() is updated to use bytes for qc->cursg_ofs instead of sectors. The field used to be used in bytes for ATAPI and in sectors for ATA. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
