Mikulas Patocka 5be6e45d18 dm bufio: don't take the lock in dm_bufio_shrink_count ...

commit d12067f428 upstream.

dm_bufio_shrink_count() is called from do_shrink_slab to find out how many
freeable objects are there. The reported value doesn't have to be precise,
so we don't need to take the dm-bufio lock.
