Commit id '44304c6eb' added the API libxlDomainAttachControllerDevice inside a conditional LIBXL_HAVE_PVUSB, but called that function outside the conditional in libxlDomainAttachDeviceLive. Similarly, the API libxlDomainDetachControllerDevice was added inside a conditional LIBXL_HAVE_PVUSB, but called outside the conditional in libxlDomainDetachDeviceLive. This patch adds the conditional LIBXL_HAVE_PVUSB around those two calls from within the switch.
