block: include discard requests in IO accounting

We currently don't do merging on discard requests, but we potentially
could. If we do, then we need to include discard requests in the IO
accounting, or merging would end up decrementing in_flight IO counters
for an IO which never incremented them.

So enable accounting for discard requests.

Problem found by Nikanth Karthikesan <knikanth@suse.de>
