Subject: [PATCH] coccinelle: adjust the confidence of fen.cocci

From: Wang Qing <wangqing@...o.com>

We scan by coccinelle according to the confidence value, then check for 
potential problems. But the accuracy of this cocci is very low,
the scan results are all wrong.

So, lower its confidence to low.
