Don Mullis f015ac3edd lib/list_sort: do not pass bad pointers to cmp callback ...

If the original list is a POT in length, the first callback from line 73
will pass a==b both pointing to the original list_head.  This is dangerous
because the 'list_sort()' user can use 'container_of()' and accesses the
"containing" object, which does not necessary exist for the list head.  So
the user can access RAM which does not belong to him.  If this is a write
access, we can end up with memory corruption.
