Agree this is SCSI.  However, can we be clear about what the
expectation is?  Host Number looks like it should be expected to change
on hot plug/hot unplug, so what is the actual problem?

I get that the driver not releasing the host is causing this, but even
if it did do instant release, when you hot plug two SCSI devices, you
stand a good chance of getting a different host number anyway.
