    tests: Fix incomplete failure check in socket test
    
    For the check "if (error != NULL)" to work as expected, the
    create_server() (and create_server_full()) functions need to make
    sure to return an error for all the possible failures, but this
    might not always be the case.
    
    Catch all the failures by testing for a NULL result instead.
