qemu: remove redundant code that adds "template" netdev name

Browse Source 
The lower level function virNetDevGenerateName() now understands that
a blank ifname should be replaced with a generated name based on a
template that it knows about itself - there is no need for the higher
level functions to stuff a template name ("vnet%d") into ifname.
