oom: suppress extraneous stack and memory dump

Suppresses the extraneous stack and memory dump when a parallel OOM killing
has been found.  There's no need to fill the ring buffer with this information
if its already been printed and the condition that triggered the previous OOM
killer has not yet been alleviated.
