Fix vdev_open_child() race on updating vdev_parent->vdev_nonrot

Updating vd->vdev_parent->vdev_nonrot in vdev_open_child()
is a race when vdev_open_child is called for many children
from a task queue.

vdev_open_child() is only called by vdev_open_children(), let
the latter update the parent vdev_nonrot member.  The update
was already there, so done twice previously.  Thus using the
same logic at the end in vdev_open_children() to update
vdev_nonrot, either we are vdev_uses_zvols() or not.
