[weiyj_lk-9Onoh4P/yGk@public.gmane.org]

From: Wei Yongjun <yongjun_wei-zrsr2BFq86L20UzCJQGyNP8+0UxHXcjY@public.gmane.org>

Fixes the following sparse warnings:

net/rds/tcp.c:59:5: warning:
 symbol 'rds_tcp_min_sndbuf' was not declared. Should it be static?
net/rds/tcp.c:60:5: warning:
 symbol 'rds_tcp_min_rcvbuf' was not declared. Should it be static?
