    Fix issue with Linux guest XHCI tablet probing.

    The USB3 spec mandates that the device-descriptor max packet size
    be 512 bytes, which requires a field size of 9 since it is a
    power-of-2.

    Linux kernels recently started validating this field, resulting in
    the table not being probed and the cursor not working in bhyve VNC.
