Patch to fix support for StorCase InfoStation

[Nick Triantos]

Hi,

I've got a StorCase InfoStation 12-bay SATA-to-FC SAN attached to my  
FreeBSD server.  It turns out that this device does not support the  
SCSI cmds to sync its cache.

The patch below can be applied to /usr/src/sys/cam/scsi/da_scsi.c to  
fix this issue, but adding this storage system to the list of quirks.

I don't know the correct procedure to submit this patch, but hopefully  
someone on this list can help.

Please let me know if I should do anything else to get this checked in.

best,
-Nick
