libata: Update queued trim blacklist for M5x0 drives
commit d121f7d0cbb875abce249dbf7eb191f9bafe80b7 upstream. Crucial/Micron M500 drives properly support queued DSM TRIM starting with firmware MU05. Update the blacklist so we only disable queued trim for older firmware releases. Early M550 series drives suffer from the same issue as M500. A bugfix firmware is in the pipeline but not ready yet. Until then, blacklist queued trim for M550. Signed-off-by: Martin K.
