Subject: [PATCH] make proxy_stream_close close target stream even on errors

When git_filter_apply_fn callback returns a error while smudging proxy_stream_close
ends up returning without closing the stream. This is turn makes blob_content_to_file
crash as it asserts the stream being closed whether there are errors or not.

Closing the target stream on error fixes this problem.
