Modified Files:
        src/sys/dev/usb: if_aue.c if_auereg.h

Log Message:
workqueue(9) has the non-evident limitation that the caller cannot reuse
the same struct work before workqueue(9) has internally started to work on
the task.

So to make sure that doesn't happen, provide a semaphore not to run the
workqueue multiple times.  It might be clearer just skip using workqueue(9)
and use a thread for about everything, but oh well, I leave that to
someone else.

Now is@ can yank his USB-to-Ethernet adapter while the interface is up.
