[Thread] fix the issue that border routing is not available after
ot-daemon restarts

This CL tries to fix issue by removing error-prone shortcircuit checks.
The checks skip configuring the ot-daemon if they think the new state
is equal to the old state. However, the old state mainainted in
ThreadNetworkControllerService may be stale which causes issues.
