blk-throttle: don't truncate the cgroup v1 iops limits
tg_set_conf() parses the limit into a u64 and stores the iops ones
through an unsigned int, so anything above UINT_MAX is truncated and a
multiple of 2^32 becomes a limit of 0. The next IO of the group then
divides by it in tg_within_iops_limit().
Clamp to UINT_MAX, which means no limit, like tg_set_limit() does on the
default hierarchy.
