In log_newpage_range(), heed forkNum and page_std arguments.
The function assumed forkNum=MAIN_FORKNUM and page_std=true, ignoring
the actual arguments. Existing callers passed exactly those values, so
there's no live bug. Back-patch to v12, where the function first
appeared, because another fix needs this.
