pata_ali: use atapi_cmd_type() to determine cmd type instead of transfer size
pata_ali was using qc->nbytes to determine whether a command is data transfer type or not. As now qc->nbytes can be extended by padding and draining buffers, these tests are not useful anymore. Use atapi_cmd_type() instead. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jeff Garzik <jeff@garzik.org>
