USB - Add support for xfer-restart-before-callback

Interrupt pipes restart their xfers.  When used for a USB
keyboard the xfer must be restarted before the callback,
even though there may be state data races, otherwise
the CTL-ALT-ESC sequence into the debugger will leave
the xfer unqueued and the keyboard will stop working.
