[PATCH] fix: domains do not get created when using vifname variable for bridged interfaces

[Patrick Scharrenberg <pittipatti@web.de>]

In the two scripts vif-bridge and vif-route the variable containing the right 
interface-name, after an interface was renamed using "ifname", is $vif.
Otherwise hotplug can't handle renamed interfaces and prevents xm from 
creating domains.

Please apply to unstable.

In 4.0.x the scripts are correct.
In unstable only vif-route contains the right variables
