[USBDRIVER]
- Register the device with the device manager only after it has been successfully
allocated to avoid a crash
- A device that failed in xhci_alloc would never get deregistered from the device manager
so it would crash when it entered xhci_start with a partially set up device extension
- Define release_adapter to HalPutDmaAdapter to fix a DMA adapter leak
[HAL]
- Export HalPutDmaAdapter
