[PATCH] cciss: direct lookup for command completions
This patch changes the way we complete commands. In the old method when we
got a completion we searched our command list from the top until we find it.
This method uses a tag associated with each command (not SCSI command tagging)
to index us directly to the completed command. This helps performance.
