mm, oom: fix potential killing of thread that is disabled from oom killing
/proc/sys/vm/oom_kill_allocating_task will immediately kill current when the oom killer is called to avoid a potentially expensive tasklist scan for large systems. Currently, however, it is not checking current's oom_score_adj value which may be OOM_SCORE_ADJ_MIN, meaning that it has been disabled from oom killing. This patch avoids killing current in such a condition and simply falls back to the tasklist scan since memory still needs to be freed.
