  Modified files:
    sys/dev/usb          if_aue.c if_auereg.h 
  Log:
  Stop INVARIANTS panics in if_aue with a stopgap.
  
  aue_tick calls several synchronous usb functions from a timeout(9),
  this is very broken since a timeout(9) is run as an interrupt
  and the usb functions tsleep.
  
  A stopgap fix is to schedule a taskqueue task from the timeout
  and defer work to that taskqueue task.
