virtio-net: check the existence of peer before accessing vDPA config
We try to check whether a peer is VDPA in order to get config from
there - with no peer, this leads to a NULL
pointer dereference. Add a check before trying to access the peer
type. No peer means not VDPA.
Fixes: 108a64818e69b ("vhost-vdpa: introduce vhost-vdpa backend")
