rds: fix building with IPV6=m
When CONFIG_RDS_TCP is built-in and CONFIG_IPV6 is a loadable
module, we get a link error agains the modular ipv6_chk_addr()
function:
net/rds/tcp.o: In function `rds_tcp_laddr_check':
tcp.c:(.text+0x3b2): undefined reference to `ipv6_chk_addr'
This adds back a dependency that forces RDS_TCP to also be
a loadable module when IPV6 is one.
Fixes: e65d4d96334e ("rds: Remove IPv6 dependency")

Allow RDS to use TCP as a transport.
This transport does not support RDMA operations.
