Use largest_zero_folio() in __blkdev_issue_zero_pages().
On systems with CONFIG_PERSISTENT_HUGE_ZERO_FOLIO enabled, we will end up
sending larger bvecs instead of multiple small ones.

Noticed a 4% increase in performance on a commercial NVMe SSD which does

gains might be bigger if the device supports bigger MDTS.
