submodule foreach: replace $path with $sm_path in example

f0fd0dc5c5 (submodule foreach: document '$sm_path' instead of '$path',
2018-05-08) updated the documentation to advise callers to favor
$sm_path over the deprecated synonym $path.  However, the example in
that section still uses $path.  Update it to use $sm_path.
