etna_resource_from_handle() is called for each plane of a multiplanar
resource, so there is no point in looping over all planes to do the
renderonly scanout import. In fact that will cause us to lose track
of the scanout imports from later planes when the earlier planes are
redoing the import, overwriting the pointer to the allocated
renderonly_scanout struct.
Drop the loop and just do the import for the current plane.
