Log Message:
- Remove the "free_list" member from scsipi_xfer.  Add "adapter_q" and
"device_q" TAILQ entries.  The former is for use by the adapter driver,
as it sees fit.  The latter is for the scsipi middle layer to track
pending xfers per device.
- Add a pending_xfers queue to scsipi_link, to track pending xfers per
device.
- Grow scsipi_link's flags to int, and add SDEV_WAITDRAIN, to indicate that
we're waiting for the pending_xfers queue to empty.
