virtio: Allow .get_vhost() without vhost_started
Historically, .get_vhost() was probably only called when
vdev->vhost_started is true. However, we now decidedly want to call it
also when vhost_started is false, specifically so we can issue a reset
to the vhost back-end while device operation is stopped.
Some .get_vhost() implementations dereference some pointers (or return
offsets from them) that are probably guaranteed to be non-NULL when
vhost_started is true, but not necessarily otherwise. This patch makes
all such implementations check all such pointers, returning NULL if any
is NULL.
