[Fix] Move the retry block not only to read the response, but also includes write command, so that it re-send the command, too. [Test] Verified on the buggy Dell AIO, it passes 30 times and should be more reliable. [Regression Potential] Low, there is no code flow change, just move the retry block to include both write and read command.
