soreuseport: fix merge conflict in tcp bind
One of the validation checks for the new array-based TCP SO_REUSEPORT
validation was unintentionally dropped in ea8add2b1903. This adds it back.
Lack of this check allows the user to allocate multiple sock_reuseport
structures (leaking all but the first).
Fixes: ea8add2b1903 ("tcp/dccp: better use of ephemeral ports in bind()")
