scsi: move host_status handling into SCSI drivers
Some SCSI drivers like virtio have an internal mapping for the host_status. This patch moves the host_status translation into the SCSI drivers to allow those drivers to set up the correct values. Signed-off-by: Hannes Reinecke <hare@suse.de>. [Added default handling to avoid touching all drivers. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
