[PATCH 4.16 077/161] usbip: Correct maximum value of CONFIG_USBIP_VHCI_HC_PORTS

[Greg Kroah-Hartman]

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

[ Upstream commit 351a8d4837ae0d61744e64262c3a80ab92ff3e42 ]

Now that usbip supports USB3, the maximum number of ports allowed
on a hub is 15 (USB_SS_MAXPORTS), not 31 (USB_MAXCHILDREN).
