mm: copy over oom_adj value at fork time
Fix a post-2.6.31 regression which was introduced by
2ff05b2b4eac2e63d345fc731ea151a060247f53 ("oom: move oom_adj value from
task_struct to mm_struct").
After moving the oom_adj value from the task struct to the mm_struct, the
oom_adj value was no longer properly inherited by child processes.
Copying over the oom_adj value at fork time fixes that bug.
