8268165: AsyncLogging will crash if rotate() fails

LogFileOutput::rotate() may leave _stream NULL because os::fopen() may return NULL due to space or inode limitations.  AsyncLogWriter::write() calls LogFileOutput::write_blocking() without null check.  Null check is added to prevent from crashing.
