CTLR_STATE_CHANGE_EVENT and CTLR_STATE_CHANGE_EVENT_REDUNDANT_CNTRL
do not require rescans to be initiated.  Current firmware filters out
these events already, but some out of date firmware doesn't, so the
driver needs to filter them out too.  Without this change and with out
of date firmware you may see the driver spending a lot of time
scanning devices unnecessarily on some Smart Arrays.

The acornscsi driver was added in v2.1.88. It has always #undef-ed
CONFIG_SCSI_ACORNSCSI_LINK near the top of acornscsi.c. And, just to be
sure, it has also always triggered a preprocessor error if
CONFIG_SCSI_ACORNSCSI_LINK was still defined. But, as far as I can see,
it has never even been possible to set SCSI_ACORNSCSI_LINK through
kconfig, or its predecessors, in the first place.

Let's remove the code involved.
