Subject: [PATCH] USB: xen-hcd: Traverse host/ when CONFIG_USB_XEN_HCD is
 selected

If no other USB HCDs are selected when compiling a small pure virutal
machine, the Xen HCD driver cannot be built.

Fix it by traversing down host/ if CONFIG_USB_XEN_HCD is selected.

Fixes: 494ed3997d75 ("usb: Introduce Xen pvUSB frontend (xen hcd)")
