pata_ali: use atapi_cmd_type() to determine cmd type instead of transfer size

Browse Source 
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.
