[libvirt] [PATCH v2 08/36] virt drivers: don't handle type=network after resolving actual network type

The call to resolve the actual network type will turn any NICs with type=network into one of the other types. Thus there should be no need to handle type=network in later switch() statements jumping off the actual type. Signed-off-by: Daniel P.
