Subject: Add factory recertified Crucial M500s to blacklist
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/
