Zach Brown abd7ffc247 scoutfs: only trace read qourum blocks after io ...

We have trace points as blocks are read, but the reads are cached as
buffer heads.  The iteration helpers are used to referenced cached
blocks a few times in each voting cycle and we end up tracing cached
read blocks multiple times.  This uses a bit on the buffer_head to only
trace a cached block the first time it's read.
