[PATCH 6/6] virtio-scsi: Set shost->max_id=1 for tcm_vhost WWPNs

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

This is currently required for connecting to tcm_vhost in order to prevent
the client LUN scan from detecting the same tcm_vhost WWPN on multiple target
IDs.
