timesync: stop re-sync on network configuration change when no link servers are confi...

This commit fixes an issue where systemd-timesyncd re-synchronizes the
system clock every time the network configuration is updated, no matter
whether link servers are actually changed.

Fixes a bug introduced by e05dd7718d0b32e039c9e0f7bf3875079d1a359d.
