[PATCH net-next] ipconfig: make two variables static

[roy.qing.li@gmail.com]

From: Li RongQing <roy.qing.li@gmail.com>

make two variables static to kill the warning:
 warning: symbol 'ic_addrservaddr' was not declared. Should it be static?
 warning: symbol 'ic_dev_xid' was not declared. Should it be static?
