Prevent memory leaks in error paths by deferring

Prevent memory leaks in error paths by deferring
allocation until we have checked for errors. Also, fix the host ID
(target #) to be one larger than the max target ID for the host. Also,
reduce the number of outstanding commands per LUN to 1 (although this
might not be needed). Also scst_lcl_ini_driver_template flags cleanup.
