That's not going to fly. Most ->remove calls are surprise removals
and thus scsi_remove_host must implcy a scsi_set_host_offline and never
call into the LLDD again. It can thusly free it's resources nicely
after it called scsi_remove_host. struct Scsi_Host itself needs
refcounting, but as soon as scsi_remove_host is called it must be gone
as far as the driver is concerned. Your approch would imply we could
imply we could get a scsi release callback long after the pci/whatever
->remove is called which is a very bad thing.
