kvm tools: Use standardized style for the virtio/net.c driver
I had a quick look at virtio/net.c and it still had quite many style
inefficiencies - all of which are patterns which i pointed out before:
- use short names for devices within the driver, so not 'net_device' but
'ndev' - everyone hacking net.c knows that this is the network driver so
'ndev' is a self-explanatory (and very short) term of art ...
- use 'pci_header' instead of the ambiguous and misleading
'virtio_net_pci_device' naming.
- do not repeat 'net' in struct net_device fields! So rename ndev->net_config
to ndev->config.
- In the kernel we generally use _lock names for mutexes. This is conceptually
more generic. So rename the net device mutexes accordingly.
- group #include lines in a topical way instead of a random mess
- fix vertical alignment mismatches
