sched: Remove cfs bandwidth period check in tg_set_cfs_period()
Remove cfs bandwidth period check from tg_set_cfs_period. Invalid bandwidth period's lower/upper limits are denoted by min_cfs_quota_period/max_cfs_quota_period repsectively, and are checked against valid period in tg_set_cfs_bandwidth(). As pjt pointed out, negative input will result in very large unsigned numbers and will be caught by the max allowed period test.
