net/rds: Fix incorrect bigger vs. smaller IP address check

net/rds: Fix incorrect bigger vs. smaller IP address check

In commit d8bd5dfb5de4 ("net/rds: use one sided reconnection during a
race"), the function rds_addr_cmp() was called without comparing the
return value to less-than or bigger-than-equal to zero.

This led to a situation where both peers thought they were the winner,
and consequently, racing RDS connections didn't form or took a long
time to form.

The issue is fixed by this commit.
