usbip: Fix USB device hang due to wrong enabling of scatter-gather
The previous USB3 SuperSpeed enabling patches mistakenly enabled
URB scatter-gather chaining, which is actually not supported by
the VHCI HCD. This patch fixes that.
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=197867
Fixes: 03cd00d538a6feb ("usbip: vhci-hcd: Set the vhci structure up to work")
