Martin K. Petersen 337d89bc18 libata: Blacklist queued TRIM on all Samsung 800-series
commit 9a9324d396 upstream.

The queued TRIM problems appear to be generic to Samsung's firmware and
not tied to a particular model. A recent update to the 840 EVO firmware
introduced the same issue as we saw on 850 Pro.

Blacklist queued TRIM on all 800-series drives while we work this issue
with Samsung.
