1.3.28 no scsi problem with ksyms

I was not able to compile the 1.3.28 kernel without SCSI support because of a
conflict within kernel/ksyms.c. I got my kernel to compile with the following
patch:

The two definitions "scsi_dir" and "scsi_hba_dir" are unresolved when the
final link comes around. I found "scsi_hba_dir"'s definition in
drivers/scsi/scsi_proc.c which does not get compiled and linked when scsi
support is turned off.

This patch is a hack. Haven't even tested booting the resulting kernel. :)
