ide: keep track of number of bytes instead of sectors in struct ide_cmd
* Pass number of bytes instead of sectors to ide_init_sg_cmd().
* Pass number of bytes to process to ide_pio_sector() and rename
it to ide_pio_bytes().
* Rename ->nsect field to ->nbytes in struct ide_cmd and use
->nbytes, ->nleft and ->cursg_ofs to keep track of number of
bytes instead of sectors.
There should be no functional changes caused by this patch.
