dm writecache: count number of blocks discarded, not number of discard bios
Change dm-writecache, so that it counts the number of blocks discarded
instead of the number of discard bios. Make it consistent with the
read and write statistics counters that were changed to count the
number of blocks instead of bios.
Fixes: e3a35d03407c ("dm writecache: add event counters")
