rustdoc: Fix testing no_run code blocks

This was a regression introduced by #31250 where the compiler deferred returning
the results of compilation a little too late (after the `Stop` check was looked
at). This commit alters the stop point to first try to return an erroneous
`result` and only if it was successful return the sentinel `Err(0)`.

Closes #31576
