Title: Fix xen bus device reference count handling to prevent leaks.

This is a somewhat minimal attempt to fix the xen device reference
counting. There are a number of comments in the code to give an idea
of what is going on. The exhaustion of resources seen while testing
vusb device plug/unplug was caused by improper reference counting
leading to leaked memory and xenbus resources. This also fixes the
same leaks when vif/vwif devices are disconnected and connected.
