3.5.7.17 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sreekanth Reddy <Sreekanth.Reddy@lsi.com>

commit 48ba2efc382f94fae16ca8ca011e5961a81ad1ea upstream.

When SCSI command is received with task attribute not set, set it to SIMPLE.
Previously it is set to untagged. This causes the firmware to fail the commands.
