libata: Do not blacklist Micron M500DC
[ Upstream commit 243918be6393f643e513a26e7882e6ae06ff7717 ] Queued TRIM got disabled on Micron M500DC drives thanks to the "Micron_M500*" pattern we had in place to accommodate the previous generation of this drive family. Tweak the blacklist entry slightly so we only disable queued TRIM for the non-DC variants of M500 drives. Signed-off-by: Martin K.
