File 0208-no_forced_virtnet.patch of Package dracut.16003

From: Fabian Vogt <fvogt@suse.com>
Subject: Don't include qemu network modules without reason

virtio-net without other network tools does not make sense
and causes various bugs, like bsc#960669.
This patch merges 90qemu-net into 90-kernel-network-modules.
