ANDROID: android-verity: Prevent double-freeing metadata
If extract_metadata() fails, it will free metadata in its own error
path, so it is safe to simply return the provided error value without
worrying about resource handling/releasing.
Moreover, if we simply return in extract_metadata()'s error path, we
can assume the thread of execution will only make it down into the
free_metadata: tag area sometime after extract_metadata()'s success,
in which case metadata will need to be freed without question.
