sched.c: Call debug_show_all_locks() when dumping all tasks

In commit v2.6.21-691-g39bc89f ("make SysRq-T show all tasks
again") the interface of show_state_filter() was changed: zero
valued 'state_filter' specifies "dump all tasks" (instead of -1).

However, the condition for calling debug_show_all_locks() ("show
locks if all tasks are dumped") was not updated accordingly.
