As coded, the module was not using pending entries to store its data locally before doing a flush to the central dshash with a timed pgstat_report_stat() call. Hence, the flush callback was defined, but finished by being not used. As a template, this is more efficient than the original logic of updating directly the shared memory entries as this reduces the interactions that need to be done with the pgstats hash table in shared memory. injection_stats_flush_cb() was also missing a pgstat_unlock_entry(), so add one, while on it.
