Clemens Backes f8379afa88 [base] Fail early in OS::Free and OS::Release
Instead of returning a boolean value, and then failing in the caller via
a CHECK, do fail directly inside OS::Free, OS::Release and similar
functions.

The PageAllocator methods still return a bool (which is always true) to
avoid changing the public API.
