USB Quirk Patch: SanDisk ImageMate CF SDDR31 (V:0x0781, P:0x0002)

[Sean Kelly]

Whenever I plug my SanDisk SDDR31 CF reader into my 5.1-BETA system,
I am told that the device doesn't support "Get Max Lun". I have added a USB
quirk to my kernel to fix this, and it seems to work perfectly. I would
appreciate if somebody would consider adding this before 5.2-RELEASE.

umass0: SanDisk Corporation ImageMate CompactFlash USB, rev 1.10/0.09, addr 2
umass0: Get Max Lun not supported (STALLED)

The patch below fixes this problem.

Unfortunately, if there is no CF card in the reader, I am greeted with more
fun messages which I am currently unable to find a fix for:

da0: <SanDisk ImageMate II 1.30> Removable Direct Access SCSI-2 device
da0: 1.000MB/s transfers
da0: Attempt to query device size failed: NOT READY, Medium not present
(da0:umass-sim0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:umass-sim0:0:0:0): CAM Status: SCSI Status Error
(da0:umass-sim0:0:0:0): SCSI Status: Check Condition

(da0:umass-sim0:0:0:0): Medium not present
(da0:umass-sim0:0:0:0): Unretryable error
Opened disk da0 -> 6

Anyway, here is the USB quirk patch which seems to be solving half the
problem.
