To prevent a module being removed whilst attached to a frontend, and hence xenbus calling into potentially invalid text, take a reference on the module before calling the probe() method (dropping it if unsuccessful) and drop the reference after returning from the remove() method. NOTE: This allows the ad-hoc reference counting in xen-netback to be removed. This will be done in a subsequent patch.
