fix drivers/scsi/imm.c in 2.5.3pre2

I've finally got the imm driver to work.  I have based this patch a patch

it works for me.  Please test this and send me any questions or comments you
may have.  If no one has any problems I'll send it to Linus.

Also, I have a longer patch that gets rid of some #includes in imm.c that are
also in imm.h.  I moved them to imm.h.  Let me know if I should post that
patch as well.  It is mainly cosmetic and also works for me.

Thanks,
Rich
