Replace max_t() with sub_positive() in dequeue_entity_load_avg()

Orabug: 27026563

This patch replaces max_t() with sub_positive() to prevent intermediate
values getting stored in cfs_rq->runnable_load_avg/runnable_load_sum.
This patch has been partially cherry picked from commit c7b50216818e
("sched/fair: Remove se->load.weight from se->avg.load_sum")
