Tracepoints are only created when Xen support is enabled, but they are also referenced within lib/swiotlb.c. So unless Xen support is enabled the tracepoints will be missing, therefore causing builds to fail. Fix this by moving the tracepoint creation to lib/swiotlb.c, which works nicely because the Xen swiotlb support selects the generic swiotlb support.
