Thanks a lot for testing. The offending commit is 816ab897.

libata: set device class to NONE if phys_offline
Reset methods don't have access to phys link status for slave links
and may incorrectly indicate device presence causing unnecessary probe
failures for unoccupied links. This patch clears device class to NONE
during post-reset processing if phys link is offline.
As on/offlineness semantics is strictly defined and used in multiple
places by the core layer, this won't change behavior for drivers which
don't use slave links.

The problem is that I don't really remember why I added this one back
then. This is incorrect because the condition should be dealt with
later in the reset logic. That didn't work quite as expected and I
ended up adding the above to work around that and it turned out wrong.
I'll dig deeper and find out what was the problem back then.
Thanks.
