virtio-net: not enable vq reset feature unconditionally

The commit 93a97dc520 ("virtio-net: enable vq reset feature") enables
unconditionally vq reset feature as long as the device is emulated.
This makes impossible to actually disable the feature, and it causes
migration problems from qemu version previous than 7.2.

The entire final commit is unneeded as device system already enable or
disable the feature properly.

This reverts commit 93a97dc520.
