Coly Li 437de04184 bcache: fix input overflow to writeback_rate_minimum 
[ Upstream commit dab71b2db98dcdd4657d151b01a7be88ce10f9d1 ]

dc->writeback_rate_minimum is type unsigned integer variable, it is set
via sysfs interface, and converte from input string to unsigned integer
by d_strtoul_nonzero(). When the converted input value is larger than
UINT_MAX, overflow to unsigned integer happens.

This patch fixes the overflow by using sysfs_strotoul_clamp() to
convert input string and limit the value in range [1, UINT_MAX], then
the overflow can be avoided.
