usb: Bump max USB_MAX_PORTS to 255

Browse Source 
* Seems more common to have > 16 USB ports on xHCI
  hubs (18 on my XPS 13 root hub)
* This fixes 'hub supports more ports than we do' error
* The FreeBSD USB driver works a lot like ours and
  sets the maximum USB ports on a hub to 255
* Doesn't solve #12885 but fixes one of the errors
