    kernel - Fix usb keyboard problems with ehci & ddb
    
    * Be sure to save the status of the xfer before reissuing the xfer
      in an interrupt pipe callback.
    
      This fixes an issue where ukbd thought the keyboard events from
      ehci were illegal because the status of the transfer was always
      IN_PROGRESS instead of COMPLETE.
    
      Interrupt pipes reissue their xfers prior to making the callback
      in order to ensure that the xfer is not somewhere in no-man's land
      if the callback enters the debugger (i.e. ctl-alt-esc).
