handover_decision: Fix condition for power budget handover attempt 

Handover attempt for power budget case should be performed every N SACCH frames,
where N = Power Budget Interval.
First measurement report with mr->nr = 0 was used for the first handover attempt
in this case, which is not correct, because first usable report should have
mr->nr = net->handover.pwr_interval-1.
Moreover using the first measurement report with mr->nr = 0 for handover attempt
could lead to unnecessary handover, because usually av_rxlev for first measurement report
from MS is worse than for following reports.
