[PATCH] [V3] net: ipconfig: avoid warning by making ic_addrservaddr static

The symbol ic_addrservaddr is not static, but has no declaration
to match so make it static to fix the following warning:

net/ipv4/ipconfig.c:130:8: warning: symbol 'ic_addrservaddr' was not declared. Should it be static?

V3: fix the title from V2
V2: make ic_addrservaddr static instead of adding to header
