Changes

power_control: always feed input values to do_avg_algo()

The purpose of the power control interval (P_CON_INTERVAL) is to
temporarily suspend the decision-making process of the MS/BS power
control algorithm, allowing time to observe the effects of a
previous adjustment.

However, input value (RxLev/RxQual) averaging must continue
uninterrupted, regardless of the power control interval.
Otherwise we're simply loosing measurement samples.
