OK, done.
Just to give background for people on linux-scsi: the original problem
which prompted this was that when a SCSI driver is loaded/unloaded
many times, the SCSI host number increases without each time (until it
wraps). This is particularly unhelpful with devfs.
To solve this, a simple patch to decrement the host counter when a
module with the last allocated SCSI number is unloaded would do
nicely, I think.
