soreuseport: fix merge conflict in tcp bind

Browse Source 
One of the validation checks for the new array-based TCP SO_REUSEPORT
validation was unintentionally dropped in ea8add2b19.  This adds it back.

Lack of this check allows the user to allocate multiple sock_reuseport
structures (leaking all but the first).

Fixes: ea8add2b19 ("tcp/dccp: better use of ephemeral ports in bind()")
