technology: Recompute hardblocked state on rfkill remove event

This fixes the case of cascading rfkill switches: if enabled, hard rfkilling
such technology might generate contradictory events.

1 - first all switches are hardblocked
2 - then one of these switch (usually: device's switch) gets fully unblocked
3 - then this same switch gets removed

Step 2 is in contradiction with step 1, so we need to care about such switch
getting removed by recomputing the hardblocked state.
