I could sponsor this change for you as it looks sane in this case, but
I'm a bit concerned that it's not the right way to go. I think the right
way is per what smartmontols-devel reply was, i.e. that we should
actually, in case of multiple temperature readings, should prefer the
one that's more common - and in that case treat the other attribute as
another value. I'm simply worried that this change could affect some of
those older HDDs that actually used 231 only to denote temperature. Do
we know if those won't get affected?

Bug description:
Hello, here's my system info
~$ lsb_release -rd
Description: Ubuntu 16.04 LTS
Release: 16.04
~$ apt-cache policy udisks2
udisks2:
Installed: 2.1.7-1ubuntu1
Candidate: 2.1.7-1ubuntu1
Version table:
*** 2.1.7-1ubuntu1 500
500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages
100 /var/lib/dpkg/status
Here's the problem: udisks2 constantly shows that my ssd temperature is 99°C (210°F), but in reality it's 30°C
~$ sudo smartctl -A /dev/sda

in the GUI app ("Disks") it shows the wrong temperature too. hddtemp
works well though:
~$ sudo hddtemp /dev/sda
/dev/sda: PNY EU SSD CS1311 240GB: 30°C
