Subject: [PATCH] view: Mark subchildren as unmapped in view_child_destroy

The subchildren lose their parent association at this point, so they
will not be able to see that the parent is unmapped.

Instead, just set the subchildren to be unmapped directly.

(cherry picked from commit 79e43b19d795d68a3916a19d9afadc4ccbb7d4db)
