target: Convert demo-mode only drivers to target_alloc_session
This patch converts existing loopback, usb-gadget, and
xen-scsiback demo-mode only fabric drivers to use the
new target_alloc_session API caller.
This includes adding a new alloc_session callback for
fabric driver internal nexus pointer assignments.
