As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt (CR_INTERRUPT) might be lost. Problem is that when device trigger CR_INTERRUPT it disables HW interrupt. Now if USB_INT_ID_REGS with CR_INTERRUPT gets lost, beacon interrupt stays disabled until beacon watchdog notices the stall. This happen very often on heavy TX. Improve watchdog to trigger earlier, after three missing beacon interrupts.
