Log Message:
Pull up following revision(s) (requested by bouyer in ticket #882):
	sys/dev/ic/ahcisata_core.c: revision 1.5
	sys/dev/ic/ahcisatareg.h: revision 1.2

Fix various error handling bugs:
- the value of the ATA error register would be computed wrongly, leading to
  bogus error values reported to wd(4)
- the channel would not always be restarted after an error, so the next
  command would not be handled by the controller
- a timeout condition would not be properly reported to wd(4), leading
  to a short transfer instead of a reset/retry
these bugs would cause a AHCI SATA channel to be stalled (no more command
processed) after a "ID not found" or "Aborted command" error reported by the
drive.
