Jim Harris 666b0fab76 For ATA_PASSTHROUGH commands, pretend isci(4) supports multiword DMA 
by treating it as UDMA.

This fixes a problem introduced in r249933/r249939, where CAM sends
ATA_DSM_TRIM to SATA devices using ATA_PASSTHROUGH_16.  scsi_ata_trim()
sets protocol as DMA (not UDMA) which is for multi-word DMA, even
though no such mode is selected for the device.  isci(4) would fail
these commands which is the correct behavior but not consistent with
other HBAs, namely LSI's.

smh@ did some further testing on an LSI controller, which rejected
ATA_PASSTHROUGH_16 commands with mode=UDMA_OUT, even though only
a UDMA mode was selected on the device.  So this precludes adding
any kind of mode detection in CAM to determine which mode to use on
a per-device basis.
