commit bf5c4136fa5ce471bdbf4cf59a813e32755fd014 upstream.

It looks like FUA support is broken on JMicron 152d:2566 bridge:

[223159.885704] sd 7:0:0:0: [sdc] Write Protect is off
[223159.885706] sd 7:0:0:0: [sdc] Mode Sense: 47 00 10 08
[223159.885942] sd 7:0:0:0: [sdc] Write cache: enabled, read cache: enabled, supports DPO and FUA

[223283.691677] sd 7:0:0:0: [sdc]
[223283.691680] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
[223283.691681] sd 7:0:0:0: [sdc]
[223283.691682] Sense Key : Illegal Request [current]
[223283.691684] sd 7:0:0:0: [sdc]
[223283.691685] Add. Sense: Invalid field in cdb
[223283.691686] sd 7:0:0:0: [sdc] CDB:
[223283.691687] Write(10): 2a 08 15 d0 83 0d 00 00 01 00
[223283.691690] blk_update_request: critical target error, dev sdc, sector 2927892584

This patch adds blacklist flag so that sd will not use FUA
