aio-stress: Fix segfaults

When the memory returned from malloc() contains some garbage, the
t[0].active_opers is not initialized to zero and the testcase segfaults
in oper_list_add() while trying to insert into the linked list:

Program received signal SIGSEGV, Segmentation fault.
0x0000000000401807 in oper_list_add (oper=0x607220, list=0x6070a0) at aio-stress.c:315
315             oper->prev = (*list)->prev;
