bcache: Populate writeback_rate_minimum attribute
Forgot to include the maintainers with my first email.
Somewhere between Michael Lyle's original
"bcache: PI controller for writeback rate V2" patch dated 07 Sep 2017
and 1d316e6 bcache: implement PI controller for writeback rate,
the mapping of the writeback_rate_minimum attribute was dropped.
Re-add the missing sysfs writeback_rate_minimum attribute mapping to
"allow the user to specify a minimum rate at which dirty blocks are
retired."
Fixes: 1d316e6 ("bcache: implement PI controller for writeback rate")
