selftests/net: timestamping: Fix bind_phc check

timestamping checks socket options during initialisation. For the field bind_phc of the socket option SO_TIMESTAMPING it expects the value -1 if PHC is not bound. Actually the value of bind_phc is 0 if PHC is not bound. This results in the following output: SIOCSHWTSTAMP: tx_type 0 requested, got 0; rx_filter 0 requested, got 0 SO_TIMESTAMP 0 SO_TIMESTAMPNS 0 SO_TIMESTAMPING flags 0, bind phc 0 not expected, flags 0, bind phc -1 This is fixed by setting default value and expected value of bind_phc to 0.
