Function ataReadExtSelfTestLog didn't swap byte-order for all little-endian variables on big-endian platform

[WHR]

Due this bug, only 1 log entry gets correctly swapped, results in wrong values being displayed on big-endian platforms.
For example:

# smartctl -l selftest /dev/sdd
smartctl pre-7.4 2023-02-12 r5455 [ppc64-linux-4.19.271-rivoreo-powerpc64-largepage] (local build)

Here the timestamps in the extended self-test log (xselftest) are incorrectly displayed except the last one.

Thanks for catching this obvious long standing (r2773) bug. BE use cases of smartctl are apparently rare.

Feel free to also provide a patch for the ChangeLog file. Use <...> for the email address if you want to provide a real name without an email address.

Applied in r5456, thanks!
