Stefano Garzarella 5840f8687f vdpa_sim: add get_config callback in vdpasim_dev_attr ...

commit 65b709586e upstream.

The get_config callback can be used by the device to fill the
config structure.
The callback will be invoked in vdpasim_get_config() before copying
bytes into caller buffer.

Move vDPA-net config updates from vdpasim_set_features() in the
new vdpasim_net_get_config() callback.
This is safe since in vdpa_get_config() we already check that
.set_features() callback is called before .get_config().
