[ Upstream commit d1b4574a4b86565325ef2e545eda8dfc9aa07c60 ] bpf_map__reuse_fd() was calling close() in the error path before returning an error value based on errno. However, close can change errno, so that can lead to potentially misleading error messages. Instead, explicitly store errno in the err variable before each goto.
