Fix memory leak in P::filter_map Probably this function isn't widely used, but anyway this wasn't working as intended. r? @eddyb Do not rollup if you want to see if max-rss change in perf.

There was a problem hiding this comment.
This is wrong, because of the ptr::read(p) call above - you need to deallocate without dropping the T value inside the Box.
