Subject: [PATCH v2] usb-storage: Add Brain USB3-FW to IGNORE_UAS

The UAS mode of BRAIN USB_HDD is reported to fail to work on several
platforms with the following error message, then after re-connecting the
device will be offlined and not working at all.

[  622.518442][ 2] sd 8:0:0:0: [sda] tag#17 uas_eh_abort_handler 0 uas-tag 18
                   inflight: CMD
[  622.527575][ 2] sd 8:0:0:0: [sda] tag#17 CDB: Write(10) 2a 00 03 6f 88 00 00
                   04 00 00
[  622.536330][ 2] sd 8:0:0:0: [sda] tag#0 uas_eh_abort_handler 0 uas-tag 1
                   inflight: CMD
[  622.545266][ 2] sd 8:0:0:0: [sda] tag#0 CDB: Write(10) 2a 00 07 44 1a 88 00
                   00 08 00

These disks have a broken uas implementation, the tag field of the status
iu-s is not set properly, so we need to fall-back to usb-storage.
