HO: Count neighbor measurements and reduce window of neigh_meas_avg
Always start with a counter of 0 for a new measurement report. If the neigh_meas_avg is caluclated over the given window, the window is reduced, if there are less measurement reports received so far. Change-Id: I1c74f27f9663a3083610c985a080fca331c19bd3
