The chlg_load use the LLOG_CAT_FIRST to process changelogs. This
values will process record in the catalog always starting with index
0 to the newest record. So when catalog reach the end of indexes and
when records are saved at the beginning of catalog, the
llog_cat_process will ignore records at the end.

This patch change the "startcat" value LLOG_CAT_FIRST to 0 to scan
the catalog from the oldest record to the newest.

Fixes: d95486c4 (lustre: mdc: polling mode for changelog reader)
