When fs_stat() queries the root / mountpoint it should return its root i_node but instead it tries to return the parent i_node which does not exist. Fix this by checking if parent is set otherwise return the root i_node. Fixes #94000. Signed-off-by: Bas van Loon <bas@arch-embedded.com> (cherry picked from commit 1dcf123)
