Message:

xhci: use device_t for bookkeeping

This started as a little refactoring to move active transfer batch to endpoint. Finding the EP in handler needs devices indexed by slot id. Then I found out we do not use the device_t extendable mechanism. Then there were a lot of errors found while doing all this…
