MPT Fusion driver 3.01.01 update

From: 	Moore, Eric Dean <Emoore@lsil.com>

This is an update for the MPT Fusion drivers 2.6 kernel.
Version 3.01.01.

This is a fix for poor performance in RAID Volumes. 
The dvStatus was being cleared for hidden physical disks
when mptscsih_slave_destroy is called.

Also, I have fixed the warning comming from mptscsih_reset_timeouts.
