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.
