mm/oom_kill.c: fix uninitialized oc->constraint
In dump_oom_summary() oc->constraint is used to show oom_constraint_text,
but it hasn't been set before. So the value of it is always the default
value 0. We should inititialize it before.
Bellow is the output when memcg oom occurs,
before this patch:
oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null), cpuset=/,mems_allowed=0,oom_memcg=/foo,task_memcg=/foo,task=bash,pid=7997,uid=0
after this patch:
oom-kill:constraint=CONSTRAINT_MEMCG,nodemask=(null), cpuset=/,mems_allowed=0,oom_memcg=/foo,task_memcg=/foo,task=bash,pid=13681,uid=0
