sched/fair: Replace source_load() & target_load() with weighted_cpuload()
With LB_BIAS disabled, source_load() & target_load() return
weighted_cpuload(). Replace both with calls to weighted_cpuload().
The function to obtain the load index (sd->*_idx) for an sd,
get_sd_load_idx(), can be removed as well.
Finally, get rid of the sched feature LB_BIAS.
