Clean up node creation in the EDT so that initialization follows member declaration. Sort registered paths by pathid so that we probe busses in order of ascending pathid. This makes hardwiring of busses without wiring individual targets do what the user expects. (submitted by tegge@FreeBSD.org) Fix an EDT node leak. Target nodes would never go away. Implement xpt_bus_deregister(). (prodded by some patches from T. Ichinoseki, but implemented differently.)
