Fix SPTPS condition in try_harder().

A condition in try_harder() is always evaluating to false when talking
to a SPTPS node because n->status.validkey_in is always false in that
case. Fix the condition so that the SPTPS status is correctly checked.

This prevented recent tinc-1.1 nodes from talking to older, pre-node-ID
tinc-1.1 nodes.

The regression was introduced in
6056f1c13bb37bf711dff9c25a6eaea99f14d31f.
