sched: Disable lb_bias feature for full dynticks

If we run in full dynticks mode, we have no way to
update the CPU load stats as typically done by
update_cpu_load_active().

Hence we need to force LB_BIAS sched feature to be off
because we can't rely on these statistics to measure a
CPU load in order to find a target for load balancing.

Instead, lets only rely on the current runqueue load
weight.
