ata: libata-scsi: improve ata_get_xlat_func

ata_get_xlat_func() is given only the opcode of a SCSI command to
determine the ATA command to translate to. This makes it impossible to
translate SCSI commands such as SERVICE ACTION IN which need a service
action field to fully specify the command.

In preparation for supporting the translation of the SERVICE ACTION IN
command with service actions different from the SAI_READ_CAPACITY_16 (READ
CAPACITY 16), change ata_get_xlat_func() to take a pointer to a SCSI
command CDB so that all fields of the SCSI command to translate can be
easily inspected.
