acornscsi: remove linked command support
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.
