Subject: [PATCH] usbip: fix VBoxUSB ioctl codes missing the FILE_WRITE_ACCESS
 bit

Every SUPUSB/SUPUSBFLT CTL_CODE was computed with Access = 0 instead of
FILE_WRITE_ACCESS (2 << 14), so the driver dispatch rejected each call
with STATUS_INVALID_DEVICE_REQUEST and the export host could not even
pass monitor GET_VERSION. Values now match usbipd-win's interop
definitions (VBoxUsb.cs / VBoxUsbMon.cs).
