...antages of Paolo's multi-queue virito-scsi, we need multi-target support in tcm_vhost first. Otherwise all the requests go to one queue and other queues are idle. This patch makes: 1. All the targets under the wwpn is seen and can be used by guest. 2. No need to pass the tpgt number in struct vhost_scsi_target to tcm_vhost.ko. Only wwpn is needed. 3. We can always pass max_target = 255 to guest now, since we abort the request who's target id does not exist.
