signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig()
Change oom_kill_task() to use do_send_sig_info(SEND_SIG_FORCED) instead of force_sig(SIGKILL). With the recent changes we do not need force_ to kill the CLONE_NEWPID tasks. And this is more correct. force_sig() can race with the exiting thread even if oom_kill_task() checks p->mm != NULL, while do_send_sig_info(group => true) kille the whole process.
