osd: Optimized EC don't apply pwlc for divergent writes

Split pwlc epoch into a separate variable so that we
can use epoch and version number when comparing if
last_update is within a pwlc range. This ensures that
pwlc is not applied to a shard that has a divergent
write, but still tracks the most recent update of pwlc.
