[pbs-devel] applied [PATCH] api: disk list: do not fail but just log error on gathering smart data

[Thomas Lamprecht]

I plugged in a USB pen drive and the whole disk list UI became
completely unusable because smartctl fails to handle that device due
to some `Unknown USB bridge [0x090c:0x1000 (0x1100)]` error.

That itself might be improvable, but most often I do not care at all
about smart data, and certainly not enough to make failing gathering
it disallow me from viewing my disks (or the smart data from disks
where it still could be gathered, for that matter!)
