It's convenient to call iova_tree_remove from a map returned from iova_tree_find or iova_tree_find_iova. With the current code this is not possible, since we will free it, and then we will try to search for it again. Fix it making accepting the map by value, forcing a copy of the argument. Not applying a fixes tag, since there is no use like that at the moment. Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
