tg_set_conf(), used for blkio.throttle.{read,write}_iops_device legacy
blkio cgroup sysfs knobs, parses limits as u64 but stores them in
unsigned int, silently truncating values above UINT_MAX. In addition
to being an obvios correctness issue, this may result in division by
zero in tg_within_iops_limit(), if the value is truncated to zero.
Reject such values with -EINVAL and explicitly use UINT_MAX as
a sentinel value for IOPS limits.
