Tetsuo Handa dd3ac9a684 net/rds: Check address length before reading address family 
syzbot is reporting uninitialized value at rds_connect() [1] and
rds_bind() [2]. This is because syzbot is passing ulen == 0 whereas
these functions expect that it is safe to access sockaddr->family field
in order to determine minimal address length for validation.
