[PATCH] net: netfilter/xt_CT.c: fix uninitialized variable

From: Cong Ding
Date: Tue Jan 15 2013 - 13:59:16 EST


If CONFIG_NF_CONNTRACK_ZONES is not defined, the variable ret might be
uninitialized when it goes to err1 through line 125 and 263 respectively.
So I change these goto err1 to return -EINVAL directly.
