Revert "qemu: Allow to plug virtio-net-pci into PCIe slot"

This reverts commit ede34470fde19c0f326cdb0dfca39fa86fd9ec16, which
was apparently written based on testing performed before commits
1e15be1 and 9a12b6 were pushed upstream. Once those two patches are in
place, commit ede34470 is redundant, and can even cause
incorrect/unexpected behavior when auto-assigning addresses for
virtio-net devices.
