lib: Add missing error handling to o_stream_cork() With ostream-file the corking could have called buffer_flush(), which could have failed and set stream_errno, but nothing would set last_failed_errno. Fixes: Panic: file ostream.c: line 59 (o_stream_close_full): assertion failed: (stream->last_failed_errno != 0)
