Bug description:
[Impact]
The scalar which control the backlight sometimes doesn't respond the first
command, so driver can't determinate whether this scalar is in charge of the
backlight.
[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.
