[PATCH] imm.c oops fix

Fix bug #3125:

This should fix the problem; however, we will need to repeat that for all
PIO SCSI drivers (another immediate victim is ppa.c).

We should start looking for sane solution; I _really_ don't like the kludge
with using ->slave_alloc() for fixups after scsi_alloc_queue().
