Handle cases like the following:
...
- controller calls scsi_done() with error XS_TIMEOUT
- scsi_done() calls sddone()
- sddone() calls disk_unbusy()
- scsi_done() calls controller to retry command (missing the
call to disk_busy())
- controller calls scsi_done()
- scsi_done() calls sddone()
- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

Redo the `wait for spin up' code. The Mach 3 method clearly doesn't work.

Also, rearrange the first open sequences a bit; SDEV_OPEN is no longer magic.

support for making dev->id_alive be set, this is for iostat to
