usb: fail usbdevice_create() when there is no USB bus
Report an error instead of segfaulting when attaching a USB device to a
machine with no USB busses:
$ qemu-system-arm -machine vexpress-a9 \
-sd Fedora-17-armhfp-vexpress-mmcblk0.img \
-kernel vmlinuz-3.4.2-3.fc17.armv7hl \
-initrd initramfs-3.4.2-3.fc17.armv7hl.img \
-usbdevice disk:format=raw:test.img
Note that the vexpress-a9 machine does not have a USB host controller.
