mod_bookmarks2: Use same default as mod_pep for max_items
Should fix the issue with max items until the proper "max" can be used,
by following the configured max.
While "max" is already in trunk, it's not easily usable in 0.11.x
This limit and option was added to mod_pep in Prosody rev aefb96a52f5f
