USB: xen-hcd: Traverse host/ when CONFIG_USB_XEN_HCD is selected

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

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.
