tgtd crashes if we want to use more than ~43 luns in a target.

To reproduce, use this bash script:

#!/bin/bash

i=1

tgtadm --lld iscsi --op new --mode target --tid 7 -T iqn.2007-02.com.example:test.break

while [ $i -ne 1024 ] ; do

    tgtadm --lld iscsi --op new --mode logicalunit --tid 7 --lun $i -b /dev/sda
    [ $? -ne 0 ] && exit
    echo lun $i
    i=$((i+1))

done

You might fail to create pthreads with both problems.

This patch enables you to create more luns (but eventually, tgtd
crashes) ?

Yes, with this patch it crashes after ~110 luns or ~60 targets.
