totemip: Be more selective when matching bindnetaddr to IP addresses

For instance, the IPs are:
eth0: 10.150.10.81/8
eth1: 10.150.10.91/24

The bindnetaddr in corosync is: 10.150.10.0 and the addr of eth1 is
selected in UDPU mode. Then the bindto address mistakenly
choosees the addr of eth0.

This does not affect binding to a fully-specific IP address.
