[PATCH v3 05/16] net: Drop vlan argument to qemu_new_net_client()

[zwu.kernel@gmail.com]

From: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

Since hubs are now used to implement the 'vlan' feature and the vlan
argument is always NULL, remove the argument entirely and update all net
clients that use qemu_new_net_client().
