[PATCH 1/2][resend][for 2.6.31 stable tree] Revert "Staging: android: lowmemorykiller.c: fix it for "oom: move oom_adj value from task_struct to mm_struct""

[KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>]

commit 0753ba01 (mm: revert "oom: move oom_adj value") reverted some
regression patch. but it didn't revert one oom retrieved driver patch.

Then, it made build error to the driver. This reverts commit
a6a9f81ccc9f5c86ccc22bbed1960a57d0316e8b too and fixes the build error.
