Subject: [PATCH] mm, oom: do not panic for oom kills triggered from sysrq

Sysrq+f is used to kill a process either for debug or when the VM is
otherwise unresponsive.

It is not intended to trigger a panic when no process may be killed.

Avoid panicking the system for sysrq+f when no processes are killed.
