Subject: [PATCH] sched.c: call debug_show_all_locks when dumping all tasks
show_state_filter() failed to call debug_show_all_locks() when specified to
dump all tasks.
Fix: call debug_show_all_locks() when !state_filter (since !state_filter
means "all tasks").

In commit 39bc89fd4019b164002adaacef92c4140e37955a 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.
