[SCSI] sd: don't fail if the device doesn't recognize SYNCHRONIZE CACHE
Evidently some wacky USB-ATA bridges don't recognize the SYNCHRONIZE
CACHE command, as shown in this email thread:
http://marc.info/?t=138978356200002&r=1&w=2
The fact that we can't tell them to drain their caches shouldn't
prevent the system from going into suspend. Therefore sd_sync_cache()
shouldn't return an error if the device replies with an Invalid
Command ASC.
