lib/blob: count clusters starting from 0 when parsing EP

Browse Source 
Previously part of function assumed that cluster count
1)means number of clusters in EP and another 2) that it is
following the active.num_clusters (akin to extent_rle).

This was incosistent and showed when using multiple
extent pages to serialize metadata.
This patch changes it to only go with 1), so it is clear
that it means number clusters within particular EP.
