[scudo] releaseToOSMaybe can fail if it can't allocate PageMap
PageMap is allocated with MAP_ALLOWNOMEM if there's no static buffer
left. So it can be failed and return nullptr without any assertion
triggered. Instead of crashing in the releaseToOSMaybe in the middle,
just return and let the program handles the page failure.
