[PULL 07/15] hw/mips: Use MachineClass->default_nic in the virt machine

[Thomas Huth <thuth@redhat.com>]

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Mark the default NIC via the new MachineClass->default_nic setting
so that the machine-defaults code in vl.c can decide whether the
default NIC is usable or not (for example when compiling with the
"--without-default-devices" configure switch).
