Patch from Stephen Cameron <steve.cameron@hp.com>

Make cciss driver retry 3rd party bus reset aborted commands up to 3 times.
(ported to 2.5 by me, original patch by Charles White)

This is needed for a multi port storage box that can have multiple hosts
connected to it, or be used in a multipath configuration.  In certain
configurations SCSI bus resets initiated by one host may affect another host.
