Modified Files:
        src/sys/arch/xen/xen: xbdback_xenbus.c

Log Message:
xbdback_disconnect() can be called twice,  from XenbusStateClosing then from
xbdback_xenbus_destroy(). The second call will wait forever as the first
already caused the xbd thread to exit.
Have xbdback_disconnect() check if we're already disconnected and if so,
do nothing.
