[PATCH] oom: handle oom_disable exiting

Having the oomkilladj == OOM_DISABLE check before the releasing check means
that oomkilladj == OOM_DISABLE tasks exiting will not stop the OOM killer.

Moving the test down will give the desired behaviour.  Also: it will allow
them to "OOM-kill" themselves if they are exiting.  As per the previous patch,
this is required to prevent OOM killer deadlocks (and they don't actually get
killed, because they're already exiting -- they're simply allowed access to
memory reserves).
