rust: pin-init: make `[pin_]chain` unwind safe
Add a drop guard before the call to the chained closure so that the value
initialized by the first stage is dropped if the closure errors or panics;
`mem::forget` the guard on success.
The previous code only ran cleanup on the explicit error path, leaking the
first-stage value if the chained closure panicked.
