Subject: Add factory recertified Crucial M500s to blacklist

From: "Guillermo A. Amaral" <[email protected]>

commit 7a7184b01aa9deb86df661c6f7cbcf69a95b728c upstream.

The Crucial M500 is known to have issues with queued TRIM commands, the factory recertified SSDs use a different model number naming convention which causes them to get ignored by the blacklist.

The new naming convention boils down to: s/Crucial_/FC/
