this is the patch to introduce a NIC model fallback to default when model
specified is not supported. It's been tested on x86_64 host with current
version of qemu-dm using the RHEL-5 i386 virtual machine and by trying to
setup the invalid (unsupported) model of NIC device. Also, the new constant
in the net.h called the DEFAULT_NIC_MODEL has been introduced to be able to
change the default NIC model easily. This variable is being used to set
the default NIC model when necessary.

It's been tested by running a guest with NIC model set to be "eee" which
is not supported and when the guest was started I tried to issue "lspci"
to list all the PCI devices and there was Realtek RTL-8239 (AS) card
which is basically the ne2k_pci card (default for Xen-4.1 qemu-dm) so
the old default has been preserved and it's being used as a fallback.
