oom: kill all threads that share mm with killed task

Browse Source 
oom_kill_task() calls __oom_kill_task() to OOM kill a selected task.
When finding other threads that share an mm with that task, we need to
kill those individual threads and not the same one.

(Bug introduced by f2a2a7108aa0039ba7a5fe7a0d2ecef2219a7584)
