scsi_debug 1.64 against 2.5.47

This is essentially the same patch that I sent earlier today. The earlier patch will apply cleanly. However since the 'sscanf("-1", "%d", &i)' bug is fixed in lk 2.5.47, this attachment removes the work around.

lk 2.5.47 does not include the 'modprobe/rmmod' fixes from Patrick Mansfield sent last week. They apply cleanly to lk 2.5.47 and with them modprobe/rmmod cycles are stable with scsi_debug.
